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 ...

An idioventricular rhythm is very similar to ventricular tachycardia (VT), except the ventricular rate is less than 60. All other characteristics of ventricular tachycardia apply, including the ...

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 ...

Lidocaine is used intravenously to treat cardiac arrest that’s caused by a ventricular arrhythmia in people who don’t respond to defibrillation. It may help improve the chance of survival. A heart ...

Non-sustained ventricular tachycardia is an abnormally fast heart rate that occurs in the lower chambers of the heart and lasts for less than 30 seconds. Tachycardia is a heart rate that is faster ...

Vektor Medical, a medical technology company transforming cardiac arrhythmia care, today announced the publication of a peer-reviewed study in EP Europace evaluating vMap-guided activation mapping and ...

What caused a patient in their 60s to develop intermittent heart palpitations and periodic weakness? At presentation to the emergency department, the patient said they had not had any significant ...

Genetic mutations can impact the heart’s structure or electrical functions, potentially leading to inherited arrhythmias. Several types of heart arrhythmias, including atrial fibrillation, Brugada ...

Patients with an implantable cardioverter defibrillator did not have a significantly lower risk of serious abnormal heart rhythms or death by consuming fish oil supplements, which had been thought to ...
