This is a challenging ECG in regards to determining if the wide QRS complex rhythm is from ventricular tachycardia or "SVT with aberrancy" such as AV nodal reentry tachycardia causing a rate-dependent ...

This ECG shows ventricular fibrillation. Disorganized wide QRS complexes of relatively low amiplitude are present at a rate of greater than 300 beats per minute. Note the sharp spikes intermittently ...

The diagnosis is sinus rhythm with interpolated premature ventricular complexes, in a trigeminal pattern, with retrograde concealed conduction. The rhythm is irregular, but there is a repeating ...

Depending on how the heart’s electrical activity appears on an EKG, a doctor may diagnose coarse or fine ventricular fibrillation (VF). Coarse VF appears as larger waves on an EKG compared with the ...

Heart rate and pulse at your wrist both indicate the rate at which the heart beats. Heart rate is measured in terms of the number of times the human heart beats in one minute. It is denoted as “beats ...

Sometimes, an abnormal EKG reading is a normal variation in a person’s heart rhythm. In other cases, it may be due to an underlying heart condition or a reaction to medication. An electrocardiogram ...

An EKG measures the heart’s electrical activity and can detect various issues, including heart attacks, rhythm abnormalities, and electrolyte imbalances. Seek immediate medical help if you experience ...

A heart arrhythmia is when your heart beats too fast, too slow, or out of sync. Some arrhythmias can be genetic. A genetic arrhythmia happens when one or both of your parents pass down a gene change ...

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 ...
