Electrocardiogram (ECG) correct answer: Since you can't see the heart beating we use a ECG to provide a picture that replicates the actual cardiac issue. Myocardial Infraction (MI) correct answer: Heart Attack -Have abnormal rhythms. -Death of cardiac muscle due to ischemia Doe the ECG machine monitor or control the hearts rhythm? correct answer: Only monitors Straight line when machine is turned on but not connected to the patient correct answer: Isoelectric = no current ...

The ECG of a client with a single-chamber atrial pacemaker should display o :## a pacemaker spike before the P wave. On an electrocardiogram (ECG), o :## the P wave represents atrial depolarization and the QRS complex represents ventricular depolarization.
