What is an ECG? An ECG is a graphical representation of the electrical activity in the heart, or as I call it, squiggles on a piece of paper which makes me seem intelligent right? We use electrodes to connect the ECG monitor to the patient and these electrodes pick up the electrical activity and cause …
After I finished school, I was told that you couldn’t diagnose a STEMI on a 12 lead if the patient had a left bundle branch block (LBBB). After furthering my studies, I have learned that… yes… yes you can. When I hear that providers can’t diagnose a in a LBBB ECG, I feel like I …

We decided to make a series where we talk about STEMI equivalents and we’ll hit on each one in different posts. To kick things off, we’re going to start with Wellen’s Syndrome. Why are we specifically hitting here? Because one of the the founding fathers of electrophysiology unfortunately passed this year and this is an …

For those who wish to hear our lecture on Youtube: here is the video Normal Cardiac Cell Depolarization It’s important to understand the effects of myocardial ischemia and how they manifest on the ECG. The normal resting potential is approximately -90 millivolts which is caused by the sodium potassium pump. This pump creates an electrolyte …
