How Could Digital Technology Make An Impact On Primary Care?
I truly hope that very soon I do not have to make an appointment at the GP when I suspect signs of a disease, but my GP will send me a message that she spotted something irregular in my latest test results and my digital health data, so I’d better visit. Let me show you in detail how primary care should be carried out in the future! Digital health should become an organic part of primary care in the future I live a fairly healthy life. I use data to improve my lifestyle and to make better decisions by optimising my sleep pattern, my physical, my cognitive or my emotional abilities; and I had several genetic tests....

Blood Pressure Meds vs Blood Thinners: What ’ s The Difference?
Conclusion In conclusion, while blood pressure medicines and blood thinners are both crucial to heart health, their roles and mechanisms of action are notably distinct. Blood pressure medication works primarily on the vascular system, aiding in reducing blood pressure by relaxing blood vessels or altering the heart’s function. On the other hand, blood thinners target the blood itself, working to prevent the formation of potentially dangerous blood clots. Throughout this article, one thing becomes undeniably clear: the importance of regular consultations with your healthcare provider. When it comes to managing m...

High-Frequency Low-Tidal-Volume Ventilation During Atrial Fibrillation Ablation Improves Long Term Outcome
Catheter ablation for pulmonary vein isolation is an important modality of treatment for paroxysmal atrial fibrillation. It is also useful for persistent atrial fibrillation, though a little less. Importance of maintaining a stable contact force of the catheter during radiofrequency ablation cannot overstressed as it contributes to lesion size and achieving transmural lesion. Both these are important in reducing re-connection of pulmonary veins, an important cause for recurrent atrial fibrillation after catheter ablation. General anaesthesia during procedure reduces the rate of pulmonary vein reconnection and hence recurr...

A young man with another episode of tachycardia. What is it? And why give adenosine in sinus rhythm?
Written by Bobby Nicholson MD and Pendell MeyersA man in his 30s presented to the ED for evaluation of chest pain and palpitations. He described it as a " jackhammering " sensation, associated with palpitations, diaphoresis, and shortness of breath, and he stated it started soon after consuming an " energy drink " (product/contents unknown).He stated these symptoms were the same as a prior episode which required cardioversion. He states that he has a heart condition which he does not know the name of and that he has felt his heart race like this once before and needed to be shocked. He was seen by a cardiologist in fo...

Clinical Examination of Cardiovascular System For Medical Students
Discussion on blood pressure is not included here as a separate topic is dedicated to it. Though the most commonly examined pulse is the radial, to check some of the characteristics, a more proximal pulse like the brachial or carotid needs to be examined. Following parameters of the pulse are routinely documented: 1. The rate: Normal rate in adult is 60-100 per minute. It is higher in children. Younger the child, higher the pulse rate. Rhythm: Regular and irregular rhythms are possible. Mild variation with respiration is called respiratory sinus arrhythmia, with higher rate in inspiration. Respiratory sinus arrhythmia may...

P wave spotting in AF is not forbidden
Fibrillation is a continuous, chaotic muscular activity. In AF, atrial muscle is expected to lose all coordinated contractions with fibrillatory waves replacing P waves. Have you ever spotted a suspicious  P wave in a strip of otherwise explicit AF?  If not, this write-up is not for you. An evolving rare theme in Atrial fibrillation  Have a look at this ECG  Here is an ECG, that was reported as AF, multiple APDs, or Possible AF, Pre AF. I suggested the term AF in transition. While few agreed, many said it is a straightforward SR with APDs, making it appear irregular RR.  But, the fact of ...

Who can answer this unusual query in mitral stenosis?
I will go with the last response. As for as I understand, we have never quantified Atrial muscle mass properly even in normality. One may be tempted to think there is no purpose to measure it, other than academic reasons. The fact that the incidence of atrial fibrillation in mitral stenosis is not linearly correlating with LA size makes us think, LA mass (Virtual LAH) may have a say in triggering AF. This post is meant for cardiology fellows. Maybe someone can do a study on this by measuring LA mass pre and post-PTMC, we might get an idea about regression as well. Meanwhile, we are well versed with infiltrative disease...

Potential disadvantages of perioperative heparin bridging
Some of the potential disadvantages of perioperative heparin bridging are risk of thromboembolism due to subtherapeutic dose, more prolonged total hospital stay and cost as well as inconvenience of heparin therapy. In addition to this, there can be excessive bleeding during re-initiation of warfarin with heparin overlap. Hence continuing warfarin through the procedure is becoming standard of care in certain special instances. This is more applicable to procedures with relatively low bleeding risk in those with high risk of thromboembolism. Cataract surgery under topical anesthesia is one such potential situation in which ...

What is secondary AF?
Secondary AF has been defined as self limited atrial fibrillation caused by a reversible etiology. Conditions which cause secondary AF are myocardial infarction, myocarditis, pericarditis, acute pulmonary disease, hyperthyroidism, ethanol intoxication, sepsis and postoperative state. It is well known that postoperative AF can increase the morbidity and ICU/hospital stay after cardiac and non cardiac surgery. Reference Quon MJ, Behlouli H, Pilote L. Anticoagulant Use and Risk of Ischemic Stroke and Bleeding in Patients With Secondary Atrial Fibrillation Associated With Acute Coronary Syndromes, Acute Pulmonary Disease, or...

What is the role of Disopyramide in HCM?
Disopyramide is a class Ia antiarrhythmic agent which can be used in hypertrophic obstructive cardiomyopathy when beta blockers alone are ineffective. Disopyramide has a negative inotropic action and is useful in reducing left ventricular outflow tract gradients in hypertrophic obstructive cardiomyopathy and does not increase the risk of sudden cardiac death. Dose reduction is recommended when QTc exceeds 480 ms. It should be avoided in those with glaucoma and men with prostatic symptoms in view of its anticholinergic action. Anticholinergic action is responsible for increase in ventricular rate with atrial fibrillation. ...

Can digoxin be given in hypertrophic cardiomyopathy?
Low dose digoxin can be used to control ventricular rate in those with left ventricular ejection fraction less than 50%, having NYHA class II-IV symptoms and permanent atrial fibrillation (Class IIb, level of evidence C, 2014 European Society of Cardiology Guidelines) Being an inotropic agent digoxin can enhance the left ventricular outflow tract obstruction. Even in those without LVOT obstruction, digoxin is not recommended, except in the specific subset mentioned above, that too only as a Class IIb recommendation. Reference 1.
