a. The pacemaker of the heart is the ___ node. b. What electrical event makes sure that the ventricles contact after the atria have contracted? The QRS complex on an ECG (electrocardiogram) represents what event of the cardiac cycle? a) Atrial depolarization b) Atrial repolarizatio...
What is the QRS complex? EKG: An EKG is a graph showing the activity of the heart. It shows the depolarization and repolarization of the heart chambers, making it possible to diagnose issues with the heart's function. Answer and Explanation:1 ...

9, 10, 11 SENIORS demonstrated a 12% RRR in event rate with the use of nebevilol.12 Beyond beta-blockers, two trials, CONSENSUS and SOLVD, underpin the guidance for using renin–angiotensin system (RAS) blockers (ACEi) in HF, demonstrating that ACEi (namely enalapril) improve survival....
Differentiating the mechanism of wide QRS complex tachycardia is critical to the proper treatment and management of patients. Tools available to the astute clinician include the medical history, signs and symptoms, ECG, cardiac imaging, cardiac device interrogation, and invasive testing. Features that ...
QRScomplextachycardiaThe electrocardiogram of a 72-year-old woman showed episodes of nonsustained narrow QRS complex tachycardia. Tracing analysis suggested that the arrhythmia was due to interpolated atrial extrasystoles occurring in bigeminal rhythm. Interpolation of atrial extrasystoles is a rare ...
