Atrial fibrillation can be a safe rhythm and not life-threatening when the rate is controlled. Medications are used to slow the electrical impulses through the AV node so that the ventricles do not try to capture each signal being produced. The reason to return people to a regular rhythm has...
a key component of female health and fertility. By contrast, changes in DBT circadian rhythm power were not predictive of the LH surge, suggesting that URs are uniquely coupled to the pre-ovulatory time of the menstrual cycle. Likewise, discrete, nightly...
Here, using a mutant allele fornr2f1awe show that a significant proportion of these fish can survive to adulthood despite their embryonic atrial chamber defects. In adultnr2f1amutants, whose hearts we found effectively lack atria, the SV, the chamber-like venous inflow tract (IFT) of which ...
A device incorporating electrodes into an Apple iPhone case allows for wireless recording of 30-second rhythm strips (LEAD I) to the cloud (AliveCor, Okla. City, OK). ECGs can be downloaded for immediate interpretation using any browser. iPhone-owning attendees of a Body Computing Conference ...
A number of variables other than LV diastolic function and filling pressures affect mitral inflow, including heart rate and rhythm, PR interval, cardiac output, mitral annular size, and LA function. Age-related changes in diastolic function parameters may represent a slowing of myocardial relaxation,...
The first onset of AF during follow-up was the observed endpoint, which was defined as an irregular rhythm with no discernible P-waves confirmed by a physician as AF after ECGs or rhythm strips were adjudicated by a critical event committee. Besides, we also studied the outcomes of stroke, ...
AMPK is a conserved serine/threonine kinase whose activity maintains cellular energy homeostasis. Eukaryotic AMPK exists as αβγ complexes, whose regulatory γ subunit confers energy sensor function by binding adenine nucleotides. Humans bearing activating mutations in the γ2 subunit exhibit a phenotype...

reviewed 10-second ECG strips hourly in 39 patients with structural heart disease and PEA/asystole arrest from all causes. They found that 82 % had HR decrease prior to arrest, mostly occurring in the last hour. Sinus bradycardia occurred in 47 %, junctional rhythm 28 %, atrial fibrillation ...
