His Bundle Pacing Cxr

Fig. 6. Cardiac output during atrioventricular sequential pacing in normal hearts. There is a 12% increase in cardiac output during His bundle pacing compared with right ventricular apical (RVA) pacing. HRA, high right atrial pacing. See ref. 5 for further discussion.

Sudden cardiac death accounts for up to half of deaths in patients with congestive heart failure. Significant numbers of such patients appear to die suddenly despite noted improvements in their cardiac function under clinical management. Hence, today it is considered that combined biventricular pacing and implantable cardioverter defibrillator therapy may improve prognosis in patients with congestive heart failure (25, 26). In addition, because the use of a transvenous defibrillation lead in the coronary sinus may significantly reduce the defibrillation threshold, the combined use of left ventricular pacing and defibrillation could have enhanced clinical significance (27). Approximately 10% of implantable cardioverter defibrillator patients are indicated for biventricular pacing at the time of implantation (28).

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
