An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac ...
Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.
Biventricular pacing alone is referred to as CRT-P (for pacing). For selected patients at risk of arrhythmias, CRT can be combined with an implantable cardioverter-defibrillator (ICD): such devices, known as CRT-D (for defibrillation), also provide effective protection against life-threatening arrhythmias.
Pacemaker syndrome is a condition that represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode, after pacemaker implantation. [1] [2] It is an iatrogenic disease—an adverse effect resulting from medical treatment—that is often underdiagnosed.
Patients who are relatively older, who need ICD for secondary prevention, or who have concomitant bradycardia requiring pacing, or heart failure requiring cardiac resynchronisation therapy are more suitable for transvenous ICD implantation. An older patient with ischemic cardiomyopathy and documented symptomatic ventricular tachycardia is a ...
A ventricular assist device (VAD) is an electromechanical device that provides support for cardiac pump function, which is used either to partially or to completely replace the function of a failing heart.
Carvana's retail unit sales in Q4 hit 114,379 vs 108,339 estimated for the quarter. For the year, Carvana reported record adjusted EBITDA of $1.378 billion, with an adjusted EBITDA margin of 10.1%
All three presentations allow distinct and easily reproducible electrical signatures as illustrated by left and right bundle branch blocks, hemiblocks, etc. The concise measurement of the time and morphology of the QRS interval allows the interventional ability to manipulate this interval with biventricular pacemakers.
