What you know about SUPRAVENTRICULAR TACHYCARDIA


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! .

A-FIB VERSUS JUNCTIONAL RHYTHMS

. ATRIAL FIBRILLATION: On your rhythm strip, the two most important characteristics are: . 1) A rhythm that’s IRREGULARLY irregular (meaning there’s no way to predict the next beat) 2) No discernible P waves . In fact, if you notice an irregularly irregular rhythm and you’re having to convince yourself that you see P waves... it’s probably A-fib (multifocal atrial arrhythmias like WAP/MAT could fit the differential) . *In my opinion: Don’t get caught up in using fibrillation waves as an absolute criteria. Very fine A-fib can sometimes produce a near isoelectric line between beats. . JUNCTIONAL RHYTHMS: The pacemaker cells surrounding the AV junction are capable of initiating regular impulses but at a slightly slower natural rate than their sinus and atrial superiors. The heart is built this way so that when the pacemaker cells with the fastest intrinsic rates are in action, those below are suppressed and function primarily to pass along the impulse from above. . For these reasons, we s...

The Pathway of Blood

Here’s a great illustration on the pathway of blood flow through the heart. It may seem easy...but you should know this cold as well as the cardiac anatomy, both of which will make procedures and understanding hemodynamics easier. . . . 💙VENOUS BLOOD- Blood flows into the heart (into the right atrium) through two major veins (the superior and inferior vena cava) as well as from the coronary sinus (cardiac venous blood from the coronaries) and then out through the first AV valve (tricuspid valve) into the right ventricle. From there blood flows into the right ventricular outflow tract, across the first semilunar valve (pulmonic valve) and into the main and then left and right pulmonary arteries. Blood then enters the lungs to become oxygenated. . . . ❤️ARTERIAL BLOOD- now that blood is oxygenated flow goes from the lungs into the left atrium through 4 veins (usually) called the pulmonary veins. From the left atrium blood flows across the other AV valve (mitral valve) and into the left ...
