Current automatic implantable cardioverter-defibrillators detect tachyarrhythmias primarily by rate-only algorithms and cannot adequately distinguish hemodynamically stable from unstable tachyarrhythmias. The responses of right atrial (mean) and right ventricular pressures (mean, systolic, diastolic, and pulse) to 64 induced and paced supraventricular and ventricular tachyarrhythmias were studi...
pulmonary hypertension (ph) is an important cause of heart failure in chronic obstructive pulmonary disease (copd). the pro brain natriuretic peptide n-terminal (nt-probnp) has been suggested as a noninvasive marker to evaluate ventricular function. however, there is no evidence to support the use of nt-probnp in monitoring the benefits of vasodilators in copd induced ph. thus, we used nt-probn...
the other parts of the right ventricular wall. Hence, estimation of the thickness only of the wall of the right ventricular inflow tract may not be accurate enough for diagnosis of early stage right ventricular hypertrophy. But even if this is the case, right ventricular wall thickness in the present study was closely correlated with right ventricular peak systolic pressure which could not be m...
The effect of retrograde cardioplegia delivered through the right atrium on right ventricular performance has not been critically examined in humans. We randomized 20 patients with right coronary artery lesions to receive cold blood cardioplegia solution either retrograde through the right atrium (group 1, n = 10) or antegradely (group 2, n = 10). The patients were similar in age, sex, severity...
Background About 3.8% of patients suffering an acute pulmonary embolism will develop chronic thrombembolic pulmonary hypertension (CTEPH). As a consequence of increasing pulmonary pressure and resistance right ventricular systolic and diastolic function deteriorate while right ventricular volumes increase. Pulmonary thrombendarterectomy (PEA) offers a potential cure with excellent longterm outc...
