Molecular autopsy or postmortem molecular testing is a set of molecular techniques used in forensic medicine to attempt to determine the cause of death in unexplained cases, in particular sudden unexplained deaths (for example sudden cardiac death). About 30% of sudden cardiac deaths in young people are not explained after full conventional ...
Sudden unexplained death in childhood (SUDC) is the death of a child over the age of 12 months which remains unexplained after a thorough investigation and autopsy. There has not been enough research to identify risk factors, common characteristics, or prevention strategies for SUDC. SUDC is similar in concept to sudden infant death syndrome ...
Based on death certificates, sudden cardiac death accounts for about 20% of all deaths in the United States. [151] [152] In the United States, approximately 326,000 cases of out-of-hospital and 209,000 cases of IHCA occur among adults annually, which works out to be an incidence of approximately 110.8 per 100,000 adults per year. [9] [81] [151]
Long QT syndrome (LQTS) is a condition affecting repolarization (relaxing) of the heart after a heartbeat, giving rise to an abnormally lengthy QT interval. [7] It results in an increased risk of an irregular heartbeat which can result in fainting, drowning, seizures, or sudden death. [1]
Most current estimates of perioperative mortality range from 1 death in 53 anesthetics to 1 in 5,417 anesthetics. [27] [28] The incidence of perioperative mortality that is directly attributable to anesthesia ranges from 1 in 6,795 to 1 in 200,200 anesthetics. [27] There are some studies however that report a much lower mortality rate.
Sudden arrhythmic death syndrome (SADS) is a sudden unexpected death of adolescents and adults caused by a cardiac arrest. However, the exact cause of the cardiac arrest, and thus the exact cause of death, is unknown. These deaths occur mainly during sleep or at rest. [7] One type of conduction defect known as Brugada syndrome can be ...
The risk of sudden death in young adults with epilepsy is increased 20-40-fold compared to the general population. [32] [33] [20] SUDEP is the number one cause of epilepsy-related death in people with pharmacoresistant epilepsy. [20] Children with epilepsy have a cumulative risk of dying suddenly of 7% within 40 years. [20]
These are typically a form of ventricular tachycardia known as Torsades de pointes which can cause faints, seizures, or even sudden death. [1] Less dangerous arrhythmias such as atrial fibrillation also occur, causing symptoms of heart racing or palpitations. However, many of those with Romano–Ward syndrome will remain free from arrhythmias ...
