During inflammation, ST-segment elevation was observed in her ECG. The ST-segment deviation was attenuated following disappearance of the abnormal Gallium-67 uptake in the LV, suggesting transmural LV voltage gradient was a cause of the ST-segment elevation.

After successful ablation recurrent torsades de pointes associated with a prolonged corrected QT (QTc) interval were initiated by polymorphic premature ventricular complexes. Genetic testing revealed a heterozygous missense mutation in the SCN5A-gene (p.Arg190Gln, Exon 5), consistent with long QT-syndrome 3. DDDR pacing following implantation of an atrial lead prevented further ventricular tachyarrhythmias.

Induction of VT was abolished by programming the PVAC-system to a pure bipolar ablation mode. Patients with implanted devices should be closely monitored when using the PVAC system in unipolar modes.

Seven years after implantation he was admitted due to cardiogenic cerebral embolism and warfarin therapy was introduced. After that, he suffered recurrent pericardial effusion for unexplained reasons. An exploratory thoracotomy revealed that the screw of the atrial lead had penetrated through the right auricular appendage wall.

In general, similar work-up regimens were used for these two arrhythmias except for coronary angiography, which was considered by one in four physicians when dealing with NSVT but by almost none for VPBs. The majority of physicians believe that it is acceptable to abstain from pharmacological therapy in an asymptomatic patient with VPBs. When considering second-line therapy almost half of the respondents would consider amiodarone in patients with NSVT whereas almost none would when dealing with VPBs. When the effect of therapy was evaluated, its influence on symptoms...

The field of telemedicine provides the opportunity for highly individualized medical management in a way that has never been possible before. Evolving medical technologies using cardiac implantable devices (CIEDs) with capabilities for remote monitoring permit evaluation of multiple parameters of cardiovascular physiology and risk, including cardiac rhythm, device function, blood pressure values, the presence of myocardial ischaemia, and the degree of compensation of congestive heart failure. Cardiac risk, device status, and response to therapies can now be assessed with these electronic systems of detection and reporting.

A single echo is associated with a recurrence risk similar to residual jump without echo. It may be suggested that pursuing a procedural endpoint up to slow pathway complete suppression may improve long-term success.

A cut-off point of 3.8 h over 24 h was associated with significant increase in the event rate. Routine assessment of AHRE should be considered with other data when assessing stroke risk and considering anti-coagulation initiation and should also prompt the optimization of cardioprotective HF therapy in CRT patients.

In the long-term, CRT appears to exert antiarrhythmic effects and to attenuate the particularly high arrhythmia-related risk of CHF patients with LBBB. The incremental benefit of adding the ICD option to CRT pacing in LBBB patients appears questionable.

Patients with CPVT are at high risk of developing life-threatening ventricular arrhythmias when untreated. A wide variety of arrhythmic event rates on conventional therapy, with β-blockers as the cornerstone, has been reported. Here, we systematically review all available studies describing the efficacy of β-blocker therapy for prevention of arrhythmic events in CPVT. Because of heterogeneity between the studies, a random-effects meta-analysis model was used to assess the efficacy of β-blocker therapy in preven...

It significantly increases costs for hospitalization. Insights into the pathophysiological factors causing POAF have been provided by both experimental and clinical investigations and show that POAF is ‘multi-factorial’. Facilitating factors in the mechanism of the arrhythmia can be classified as acute factors caused by the surgical intervention and chronic factors related to structural heart disease and ageing of the heart. Furthermore, some proarrhythmic mechanisms specifically occur in the setting of POAF. For example, inflammation and beta-adrenergic activation have been shown to play ...

The main indication for the procedure is the occurrence of multiple shocks or electrical storm, while prophylactic ablation is only rarely performed. The epicardial approach is seldom used and mostly only after failure of endocardial ablation. The main ablation strategy is targeting the clinical VT only by substrate mapping and ablation, and by targeting fractionated potentials with utilization of modern electroanatomical mapping systems. Still, a considerable number of centres frequently perform the procedure using conventional mapping catheters only.

The electrodes were covered by a connective tissue sheath as a result of thrombus organization. This process persisted most frequently around ICD ventricular electrodes. Only borderline differences were found between the histological findings around steroid-eluting and non-steroid-eluting PM ventricular electrodes.

However, we have known for at least a decade that pacing from the right ventricle (RV) apex can induce left ventricle (LV) dysfunction, atrial fibrillation, heart failure, and maybe an increased mortality. Although pacemaker manufacturers have developed successful pacing algorithms designed to minimize unnecessary ventricular pacing, it cannot be avoided in a substantial proportion of pacemaker-dependent patients. Just as there is undoubted evidence that RV apical pacing is injurious, there is emerging evidence that pacing from the RV septum is associated with a shorter duration of activation, improved h...

This may be due to competing mortality risks in this population that attenuate the benefit of the ICD in reducing arrhythmic death. Age, ejection fraction, and kidney disease severity can be used to risk stratify patients before device implantation.

Therefore, AF CFE sites do not necessarily identify regions of an abnormal atrial substrate. However, this does not exclude the possibility that CFE might identify a focal driver or source occurring in a region of normal atrial myocardium.

We found that the PA-TDI was independently prolonged in patients with a history of AF, hypertension, valve disease, higher age, and a higher BMI. Signs of diastolic dysfunction, valve incompetence, and enlarged atrium or aortic root on the echocardiogram were associated with a prolonged PA-TDI. This suggests that early and aggressive treatment of hypertension, diastolic dysfunction, and obesity could prevent intra-atrial conduction delay.

In this review, we provide a concise overview of the data regarding anticoagulation and antiplatelet therapy in arrhythmia device surgery. Also, we critically discuss risk factors and procedural parameters that are potentially associated with haemorrhagic untoward events in this setting. Of note, current evidence suggests that heparin bridging therapy in patients on chronic anticoagulation and dual-antiplatelet therapy are associated with increased risk of pocket haematoma formation.

Despite the clear association between AF and death, stroke, and other cardiovascular events, there is no evidence that rhythm control treatment improves outcome in AF patients. The poor outcome of rhythm control relates to the severity of the atrial substrate for AF not only due to the underlying atrial remodelling process but also due to the poor efficacy and adverse events of the currently available ion-channel antiarrhythmic drugs and ablation techniques. Data suggest, however, an association between sinus rhythm maintenance and improved survival. Hypothetically, sinus rhythm may also lead to a lower risk of stroke and heart failure.

After percutaneous subxiphoid puncture, steerable 9F endoscope and 7F irrigated-tip catheters were advanced into the epicardial space. Epicardial vessels were visualized, and basal fat was distinguishable. Lesions created by the irrigated-tip catheter could be also appreciated on the epicardial surface. The endoscopic pericardial procedure was successful and may increase the efficacy and safety of epicardial irrigated radiofrequency catheter ablation.

Atrial fibrillation is strongly associated with increased risk of morbidity, including stroke and thromboembolism. There is growing awareness of the economic burden of AF due to ageing populations and constrained public finances. A systematic review was performed (1990–2009). Cost studies for AF or atrial flutter were included; acute-onset and post-operative AF were excluded. Total, direct, and indirect costs were extracted. Of 875 records retrieved, 37 studies were included. The cost of managing individual AF patients is high. Direct-cost estimates ranged from $2000 to 14 200 per patient-year in the USA and from 450 to 3000 in Europe. This is comparable with other chronic con...

Although they all refer to the same scientific data and agree in the majority of AF management, interpretation, and weighing of study results are quite different in some aspects. While recommendations for stroke risk assessment and prophylaxis are rather conservative in the ESC guidelines, the CCS guideline recommendations are more conservative with regard to lenient rate control and the ACCF/AHA/HRS recommendations are rather strict with regard to rhythm manageme...

On physical examination severe hypokalaemia and long QT syndrome were apparent. During potassium (K+) supplementation we simultaneously observed QT interval recovery. This is the first report of continuous documentation of the QTc duration during serum K+ rise, highlighting the necessity of electrocardiogram documentation and serum potassium correction in appropriate patients.

A drop was observed in the DF value after isolation of the right PV. However, after left PVI this decrease was smaller.
