This ECG shows ventricular pacing. Note the pacer spike prior to each QRS complex, most apparent in leads V5 and V6. The P waves appear sinus in origin and have no association with the QRS ...

Technically, the diagnosis of an anterior myocardial infarction on an ECG has never been validated in the setting of a paced rhythm, however that was the case in this ECG. There was acute ...

The rhythm is regular at a rate of 78 beats/min. Before each QRS complex, there are two pacing stimuli (+,v) with a very short interval (0.06 sec) between them. They are both ventricular pacing ...

Ventricular paced rhythm was detected on 12-lead ECG. The widespread opinion that this constellation does not permit a diagnosis of ischemia on 12-lead ECG is not accurate, as this example shows.

As part of the evaluation, a 12-lead ECG is obtained ... atrial-sensed and ventricular-paced (Figure 2). There is a regular rhythm at a rate of 110 beats/min. P waves occur before each QRS ...

Ventricular tachycardia ... when your heart rhythm looks more steady from beat to beat when your doctor checks the electrical activity with an electrocardiogram (EKG). Polymorphic VT is a very ...

Electrocardiogram (ECG) recordings and measurements of optical action potentials confirmed that the device could deliver effective ventricular pacing, driving the rhythm of the heart to treat the AV ...

Sometimes, an extra heartbeat that starts in the lower ventricle disturbs your regular heart rhythm. It’s known as a premature ventricular ... node acts as a natural pacemaker, creating the ...

a doctor may diagnose coarse or fine ventricular fibrillation (VF). Coarse VF appears as larger waves on an EKG compared with the waves relating to fine VF. VF is an atypical heart rhythm that can ...
