WebCourse Lecturer Date Lecture Page 5 of 5 Chamber Hypertrophy More cells, more electrical activity, leads to a signal with bigger amplitude. On EKG paper, one big vertical box (5mm) represents .5 mV. (Odds of us being held to the following details is low, I asked Dr. Weismann and he said we just need to know “general concept” for chamber hypertrophy, … WebT wave alternans (TWA) is a periodic beat-to-beat variation in the amplitude or shape of the T wave in an electrocardiogram (ECG or EKG) TWA was first described in 1908. At that time, only large variations ("macroscopic" TWA) could be detected. Those large TWAs were associated with increased susceptibility to lethal ventricular tachycardias .
