Abstract

Resting heart rate (HR) associates with cardiovascular outcomes in the general population and in patients with hypertension and heart failure. The accuracy of pulse rate acquired by 24-h ambulatory blood pressure monitoring (ABPM-PR) in comparison with Holter-ECG HR (Holter-HR) is unknown. We aimed at investigating the accuracy of ABPM-PR when compared with Holter-HR. The current study included 1500 patients of a general cardiology outpatient unit undergoing simultaneous Holter and ABPM recordings. ABPM-PR differed marginally from Holter-HR by 0.55 bpm for 24-h average [95% confidence interval (CI): 0.37-0.73, P < 0.001], 1.27 bpm for daytime (95% CI: -0.98-1.56, P < 0.001) and 0.63 bpm for night-time (95% CI: 0.40-0.86 bpm; P < 0.001). The absolute delta between 24-h Holter-HR and ABPM-PR was less than 5 and less than 10 bpm in 1363 (91%) and 1458 (97%) patients, respectively. 24-h ABPM-PR more commonly underestimated than overestimated (7 versus 2%) 24-h Holter-HR by at least 5 bpm. The mean difference between Holter-HR and ABPM-PR was higher (+1.9 bpm; 95% CI: 0.9-3.0; P < 0.001) in patients with than without atrial fibrillation. There was no significant difference between Holter-HR and ABPM-PR in patients without supraventr...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
