What does an EKG represent during a typical cardiac cycle? ___ is the stretch of the heart wall due to the load to which a cardiac muscle is subject before shortening. a. systole b. diastole c. preload d. afterload The first heart sound (lub) is corr...
What event(s) should occur during a QRS interval on an EKG? In reference to ECG (electrocardiogram): What does QRS complex represent? What might be occurring if there are extra P waves than QRS complexes on an EKG and the heart rate is 50 bpm? Explain. ...
In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect?ECG:An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. Th...
