SCA is an electrical problem with the heart that causes a dangerously fast heart rhythm (ventricular fibrillation). The rapid, irregular heart rhythm causes the heart to quiver rather than pump. When the heart stops pumping blood, oxygen cannot reach the body and brain. If not treated immediatel...
Rapidly dropping pounds is associated with a loss of muscle mass and other undesirable effects—including looking older.
535 Heart rate variability response to rapid transition from supine to standing position predicts sudden death in patients with moderate to severe congestive heart failuredoi:10.1016/S1567-4215(03)90341-9SmetaninaI.N.YavelovI.S.AbramkinD.V....
Communities that institute public CPR education, use of AEDs, and rapid activation of 911 emergency medical services have dramatically increased survival rates from sudden cardiac arrest.Unfortunately, because the brain is so sensitive to the lack of oxygen and blood flow unless treatment occurs within...
A GEM score ≥ 0.69 was used to define a likely damaging genetic variant (GEM-damaging), based on the observation this threshold recovered 95% of true positive cases in a cohort of critically ill newborns undergoing rapid genome sequencing [24]. Control cohort The control cohort of 211 ...
SCA results from sudden disruptions in the heart’s electrical activity, leading to ineffective blood pumping and rapid loss of consciousness and pulse. Without immediate interventions like cardiopulmonary resuscitation and defibrillation, SCA is overwhelmingly fatal. Global survival rates for out-of-...
or a squeezing or aching sensation in your chest or either arm that may spread to your neck, jaw or back, nausea, indigestion, heartburn or abdominal pain, shortness of breath, heart palpitations, rapid or irregular heartbeats, cold sweat, lightheadedness or sudden dizziness, regardless of ge...
a particularly fast or slow heartbeat, irregular jumping, and so on can all lead to palpitations. Among the three situations, there is no need to worry about a fast and irregular heartbeat. This sudden heartbeat is not a big deal. Firstly, some rapid heartbeats are physiological and there...
Notably, KCNH2 which encodes the Kv11.1 channel that regulates the rapid component of the delayed rectifier potassium current; and KCNQ1 which encodes the Kv7.1 channel that regulates the slow delayed rectifier current are important targets. Several KCNH2 and KCNQ1 mutations tare present in long ...
A few of the causes of SUD identified at necropsy (seeSupplementary Materials Table S1) are not typically associated with rapid death and usually have premonitory signs, such as portosystemic shunt and hyperthyroid. In humans, SUD may occasionally be caused by a seemingly chronic disease such as...
