Brugada syndrome was described as a cause for the sudden unexplained cardiac death syndrome seen in Thai men in 1997. [50] The first genetic mutations affecting the SCN5A gene associated with the syndrome were identified by their brother Ramon Brugada in 1998, [ 13 ] with many more mutations affecting at least 19 genes subsequently identified ...
A 2011 autopsy-based study found that sudden death was attributed to a cardiac condition in 79.3% of cases, and was unexplained in 20.7%. [3] In the Philippines, sudden adult death syndrome (or in their term, bangungot) is mainly caused by the Brugada syndrome. [14]
Because the heartbeat is dependent on the proper movement of ions across the surface membrane, cardiac channelopathies make up a key group of heart diseases. [3] Long QT syndrome , the most common form of cardiac channelopathy, is characterized by prolonged ventricular repolarization, predisposing to a high risk of ventricular tachyarrhythmias ...
Long QT syndrome is estimated to affect 1 in 7,000 people. [6] Females are affected more often than males. [6] Most people with the condition develop symptoms before they are 40 years old. [6] It is a relatively common cause of sudden death along with Brugada syndrome and arrhythmogenic right ventricular dysplasia. [3]
It is calculated as the time from the start of the Q wave to the end of the T wave, and approximates to the time taken from when the cardiac ventricles start to contract to when they finish relaxing. An abnormally long or abnormally short QT interval is associated with an increased risk of developing abnormal heart rhythms and sudden cardiac death.
The Mayo Clinic Diet is a diet book first published in 1949 by the Mayo Clinic's committee on dietetics as the Mayo Clinic Diet Manual. [1] Prior to this, use of the term "diet" was generally connected to fad diets with no association to the clinic.
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1]
