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 ...

There are only a few sinus rhythm QRS complexes available to examine on this ECG. Using lead V1 an incomplete right bundle branch block is seen. A prolonged QT interval is present that extends all the ...

Patients suffering from refractory ventricular tachycardia, a life-threating heart condition, who are not suitable for ...

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 ...

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 ...

Johns Hopkins researchers built a virtual replica of each patient’s heart, simulated the electrical circuits causing a ...

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 ...
