He was defibrillated, but they also noticed that he was being internally defibrillated and then found that he had an implantable ICD. He was unidentified and there were no records available After 7 shocks, he was successfully defibrillated and brought to the ED. Tachycardia exaggerates ST Elevation in LBBB and Paced rhythm 5.

Permanent pacer placement Later, a biventricular pacer was placed for " Cardiac Resynchronization Therapy (CRT) " (This is indicated for patients with LBBB and QRS duration > 130 ms and heart failure and vastly improves heart failure). Even with tachycardia and a paced QRS duration of ~0.16 J Am Coll Cardiol.

The above ECGs show the initiation and continuation of a polymorphic ventricular tachycardia. Polymorphic ventricular tachycardia can be ischemic, catecholaminergic or related to QT prolongation. She spontaneously converted (Defibrillation was not performed). NT-pro-BNP peaked at 4831, consistent with heart failure.

CRT is used in heart failure with reduced ejection fraction. According to the Universal Definition and Classification of Heart Failure, heart failure with reduced ejection fraction has left ventricular ejection fraction of 40% or less. CRT stands for cardiac resynchronization therapy.

Arrhythmias : A leadless pacemaker-defibrillator system provides antitachycardia pacing for ventricular tachycardia in patients with subcutaneous ICDs. Coronary Heart Disease : Initiate beta-blockers in patients with acute MI and normal LVEF unless contraindicated or if they have heart failure.

But while compressing here in a patient with heart failure, it can elicit pain because there could be tender hepatomegaly in patients with heart failure. That occurs in right heart failure and constrictive pericarditis. One is ventricular tachycardia with regular retrograde activation.

He denied any known medical history, specifically: coronary artery disease, hypertension, dyslipidemia, diabetes, heart failure, myocardial infarction, or any prior PCI/stent. Despite immediate chest compressions, and multiple rounds of defibrillation, he could not be resuscitated. Breath sounds were clear in all lung fields.
