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....
This mechanism can break down in a variety of ways, but the final pathway in sudden death is the same: the electrical system is irritated and fails to produce electrical activity that causes the heart to beat. The heart muscle can't supply blood to the body, particularly the brain, and t...
Learn about sudden cardiac arrest, an electrical problem with the heart that triggers a dangerously fast heart rate.
Such remodeling, termed athlete's heart, permits enhanced filling of the left ventricle in diastole and augmentation of stroke volume allowing generation of a large and sustained cardiac output even at rapid heart rates. The magnitude to which this adaptation occurs is influenced by several ...
“evolutionary care package” represent interactional, contingent, multisensory opportunities for the rapid experience-based learning of regulatory behaviors and can therefore be regarded as built-in stimuli for maturational advancement. Growing up within the evolved frame of proximal care may indeed be ...
It is always important to demonstrate a clinical picture consistent with cardiac arrest (eg, in the setting of ventricular pre-excitation rapid antegrade conduction via the accessory pathway during AF or programmed atrial stimulation), to ensure that such findings are not incidental bystanders and the...
Firefighting leads to a rapid increase in heart rate initiated by sympathetic physiologic arousal from the fire alarm bell. Subsequently, maximal or near-maximal heart rates are achieved during physically strenuous firefighting activities. Perhaps of more functional significance, our work has shown a red...
Rapidly dropping pounds is associated with a loss of muscle mass and other undesirable effects—including looking older.
a baby experiences rapid brain growth and developmental changes that affect sleep patterns, cardiorespiratory control, metabolism, and physical ability. so when a more mature baby is placed in a sleep environment with pillows or loose bedding, for example, they may be able to lift their head, sh...
“Sudden” death does occur in a number of acute catastrophic neurological diseases or chronic neurological illnesses with acute decompensation. 1 The term “rapid death,” rather than “sudden death,” may be more appropriate in...
