What happens to the duration of the QRS complex on an electrocardiogram when heart rate increases due to exercise? What might be occurring if there are extra P waves than QRS complexes on an EKG and the heart rate is 50 bpm? Explain. ...
What causes an abnormal T wave in an ECG? What are some expected ECG changes with ischemic heart disease? In an ECG or EKG , if the P wave has a shorter duration, what does that mean is happening in the heart? What causes peaked P waves on a...
What does small P wave mean? A short P‐wave duration isa marker of a higher rate of atrial fibrillation recurrences after pulmonary vein isolation procedure. Can you have 2 P waves? In blocks with 2:1 conduction,two P waves occur for every QRS complex, indicating every other impulse is b...
