Results Of the 230 HCM patients included in this study (age 54 卤 16 years; 138 male; LVOT pressure gradient at rest 45 卤 39 mmHg), 115 (50%) patients had SDB. HCM patients with SDB were recorded to have higher mean HR (71 vs. 67 bpm; p = .002, adjusted p = .001), and ...
The volunteers underwent a cardiopulmonary exercise test, spirometry and a register of both resting heart rate variability (HRV) in the supine and seated positions along with HRV during the respiratory sinus arrhythmia maneuver (M-RSA). Results: At rest in supine, asthmatic volunteers presented a ...

Increases in exercise intensity are known to reset, in an upward and rightward direction, the arterial baroreflex (ABR) control of heart rate (HR) and mean arterial pressure (MAP). ABR function during recovery from exercise has not been extensively studied and therefore is unreported in the ...
How does a sudden drop in blood pressure affect heart rate, stroke volume, and cardiac output? Would the same occur with a rising blood pressure? If not, why? What can cause supraventricular tachycardia? What causes rapid heart rate at rest?
Heart Rate Variability Components View LargeDownload A, The high-frequency (HF) component, an indicator of vagal activity, was significantly decreased in the e-cigarette users compared with nonuser control individuals (mean [SEM], 46.5 [3.7] nu vs 57.8 [3.6] nu, P = .04). B and C...
Epinephrine does what to heart rate? A patient's heart rate at rest was 72 beats per minute. The patient then walked at a steady pace on a treadmill for 2 minutes. After 2 minutes, the patient's heart rate had incre...

Heart rate variability recordings Heart rate variability was assessed in a sitting position in a 23 ± 2 °C room temperature. After a 5-min period at rest, the measurements with duration of 5 min were performed by iFeel HRV Sensor (iFeel Healthy Inc., Israel) and emWave Pro (Heart...
An addi- tional group of rats (n=9) was used for measuring the blood pressure and heart rate for STZ-induced diabetes. The pro- tocol for our study was approved by the Institutional Ani- mal Care and Use Committee at the University of Mississippi Medical Center. Plasma glucose, serum ...
