We report extremely prominent heart rate oscillations associated with slow breathing during specific traditional forms of Chinese Chi and Kundalini Yoga meditation techniques in healthy young adults. We applied both spectral analysis and a novel analytic technique based on the Hilbert transform to quantify these heart rate dynamics.

OBJECTIVE: To assess the effects of a 12-week Tai Chi exercise program on sleep using the sleep spectrogram, a method based on a single channel electrocardiogram (ECG)-derived estimation of cardiopulmonary coupling, previously shown to identify stable and unstable sleep states. METHODS: We retrospectively analyzed 24-h continuous ECG data obtained in a clinical trial of Tai Chi exercise in patients with heart failure.

BACKGROUND: Carotid sinus hypersensitivity (CSH) has always been described in patients in sinus rhythm; we did not find reports of CSH in patients with chronic atrial fibrillation (AF). After the observation of bilateral CSH in a patient with chronic AF admitted to our Division for syncope, we began to systematically study patients with chronic AF and neurological disturbances to evaluate carotid sinus stimulation effects upon cardiac activity and arterial blood pressure in these subjects.

OBJECTIVE: The purpose of this study was to investigate the immediate effects of head-neck massage on heart rate variability (HRV), mood states, and pressure pain thresholds (PPTs) in patients with chronic tension-type headache (CTTH). METHODS: Eleven patients (8 females), between 20 and 68 years old, with CTTH participated in this crossover study. Patients received either the experimental treatment (massage protocol) or a placebo intervention (detuned ultrasound).

The laboratory mouse is a facultative daily heterotherm in that it experiences bouts of torpor under caloric restriction. Mice are the most frequently studied laboratory mammal, and often, genetically modified mice are used to investigate many physiological functions related to weight loss and caloric intake. As such, research documenting the cardiovascular changes during fasting-induced torpor in mice is warranted. In the current study, C57BL/6 mice were implanted either with EKG/temperature telemeters or blood pressure telemeters.

OBJECTIVE: To explore the circadian distribution of premature ventricular contractions (PVCs) in patients with viral myocarditis (VM) according to the theory of chronomedicine in traditional Chinese medicine (TCM) in order to find out the scientific evidence for a reasonable administration time. METHODS: Two hundred and forty patients with VM were enrolled and electrocardiograms were examined for all by Holter monitor. The circadian distribution of PVCs was evaluated according to the theory of chronomedicine of TCM about time periods corresponding to five zang viscera.

BACKGROUND AND OBJECTIVE: High-intensity frequency ultrasound (HIFU) can achieve pulmonary vein isolation (PVI), but severe complications have happened. An esophageal temperature (ET)-guided safety algorithm was implemented. We investigated medium-term outcome. METHODS: After left atrial access, HIFU was applied until complete PVI.

This study was designed to determine whether power spectral analysis (PSA) of heart rate variability (HRV) can detect change in autonomic tone following a relaxation intervention called therapeutic touch (TT). Thirty healthy subjects underwent TT by one of three TT practitioners using the steps developed by Krieger and Kunz (The Therapeutic Touch, Prentice-Hall, 1979). Both subjects and TT practitioners were monitored by continuous electrocardiographic monitoring (Holter) before (15 minutes), during, and after (15 minutes) TT was administered.
