The study by Jouven et al supports the view that resting heart rate is an important predictor of cardiovascular mortality, in particular of sudden death in men. This finding is in keeping with previous results from the Framingham Study in adult subjects and from the CASTEL study in elderly ...
We found a non-linear association between resting heart rate and SCD; the value of ≥ 90 beats per/min was accompanied by 72% increased risk. In the meta-analysis including five prospective studies, the researchers found a linear association between heart rate with SCD, and every 10 numb...
while the back is being firmly pressed to the ground imposes a mechanical limitation on ventilation, venous return to the heart, and cardiac output. Granted, chest compression was an entirely unlikely culprit, this letter is important in that it represents a very EARLY recognition of the dangers...
Thus, because of the changing autonomic control or modulation of the heart rate throughout the day, the high- and low-frequency power components are not stationary, and their link to specific physiology is therefore less well defined. Analysis of these bands from short-term recordings during ...
Obviously, risk factors alone are not able to explain the epidemiological record of SIDS. Apparently, the “risk currency”—the classic value in SIDS research—has a floating exchange rate. For some infants, a given risk may have a very high value; for others, its worth may be very smal...
According to an article in a medical journal, among those infants who face a high risk of crib death are those who have: a family history of SIDS (especially brothers or sisters); seizure disorders associated with apnea (lack of breathing); Hyaline membrane disease, or prematurity. ...

While this setup facilities comprehenssive and high-quality recordings, due to the intermittent nature of these short-term recordings, we likely missed some instances of spontaneous epileptiform discharges, clinical seizures, arrhythmias, and the cascade of neuro-cardiac dysfunction leading up to ...
In some cases, beta-blockers should be combined with high thoracic left sympathectomy (38). When still ineffective, pacemaker implantation to ensure stable heart rates may be necessary. If risk remains, implantation of an implantable cardioverter-defibrillator (ICD) is warranted. This should always...
suddenly be made more visible using a simple bedside test that requires a subject to suddenly stand up. When standing, at-risk patients will experience a measurable difference in a portion of their heart rate called the QT interval. The difference can be detected by an electrocardiogram (ECG)....
