The rhythm is regular at a rate of 120 beats/min. A pacemaker stimulus occurs before each QRS complex (→). This is ventricular pacing. Because the pacing rate is 120 beats/min, the mode of pacing must ...

The diagnosis is sinus tachycardia, right ventricular pacemaker, P-wave synchronous ventricular pacing (A-sensed V-paced), pseudo second-degree AV block due to failure of atrial sensing. There is a ...

SUDDEN death in persons with artificial pacemakers is a continuing and disturbing problem. Causes include pacemaker-catheter displacement, electric-component failure, broken wires and rising pacing ...

Formal systems engineering methods have been adopted by many industries including medical device manufacturing. In particular, the approach is used in pacemaker development. According to a paper from ...

The human heart is a highly complex pump made of muscle, complete with its own electric power system, supplying the energy and oxygen it needs to function. The heart’s pumping action is regulated by ...
