SUPRAVENTRICULAR TACHYCARDIA  (SVT)? is a common abnormality you will encounter in training. It is commonly associated with a rentrant loop (large “macro” or small “micro”) that allows rapid conduction from the atrium to the ventricle. . Most commonly SVTs are narrow complex regular tachycardia. The most common  SVT  is sinus tachycardia! When most people think of SVTs they think of AVNRT (Short RP tachycardia) and AVRT (wolf Parkinson’s white syndrome). SVTs are managed by recognizing the rhythm on a 12 lead EKG with a narrow complex tachycardia (usually with rates >150 bpm). SVTs more commonly occur in people with structural normal hearts (however not always true i.e congenital heart disease) and are often treated with AV nodal blockers like beta blockers, CCBs, and adenosine. SVTs are very treatable with procedures called ablations so don’t be afraid to consult your neighborhood Electrophysiologists! . Svt Supraventri...

What is Ectopic Beats? Ectopic beats are abnormal heartbeats, which arise from either the top or the bottom chambers of the heart, and these are not your natural pacemaker beats of the heart, so, for example, in a typical 24-hour period, your natural pacemaker generally gives you 100,000 heartbeats in that time period. Now we would say that ectopic beats that arise from other sites may occur, 50 to say 400 times in that 100,000 cycle, which occurs over a 24-hour period. Now ectopic beats can be felt by patients as palpitations and, for example, the major symptom of an ectopic beat. Is an extra heartbeat or a skipped heartbeat, and that’s when you feel your heart lurching or when you feel an extra strong heartbeat that only occurs momentarily more rarely. You get ectopic beats that occur in quick succession, and this would be something like this. Where you have one ectopic beat one normal beat one atopic beat or where you have their topic beats that go maybe four five or s...

Catheter ablation is not unlike other branches of medicine or life in general. The more you do the better you are. And the better is not just from the success standpoint but also from a risk minimization standpoint. One of the major questions we get is what is the success rate of these procedures? The first thing we have to define is, I think us as electrophysiologists and certainly in a research and a clinical setting, we try to define success as freedom from all arrhythmias, both those you feel and those you might not feel; which we verify that with some kind of monitoring device after the ablation; off of all drug therapy. So our goal is to get patients off anti-arrhythmic drug therapy, have them free of symptomatic arrhythmias — the ones you feel — and then also have them free of asymptomatic arrhythmias, ones you might not feel during sleep or other times during the day. That’s a pretty steep bar. Now the challenge with atrial fibrillation ablation is the ablation takes...
