Cardiac memory is an uncommonly recognized entity in which T wave inversions on electrocardiogram (EKG) appear consistent with ischemia. Persistent deep T wave inversions are seen after return of normal depolarization in leads where the T waves were normal before pacing. These changes are generally ...

ventricular pacing at a rate 10 to 40 beats faster than the intrinsic rhythm. Pacing-induced acceleration orventricular fibrillationmay occur, so adefibrillatorshould always be immediately available. In patients with ventricular tachycardia who are hypotensive or have impaired consciousness, immediate ...
When the SA node does not function properly, the AV node takes over pacing the heart and produces what is known as a junctional rhythm. Explain why we would NOT see a P wave on the EKG of a patient with such a rhythm. Describe a typical EKG in ...
Definition (MSH)An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be pa...
When VP rates were more than 130bpm, both LV global and LV segments sometimes showed irregular motion while the EKG remained normal pacing EKG, which included: (1) multiple construction and diastole in one heart cycle; (2) A large variability of construction amplitude in several consecutive ...
