The Heart Rhythm Society is an international non-profit organization that promotes education and advocacy for cardiac arrhythmia professionals and patients. The society was founded in 1979 and counted over 7,500 members from over 90 countries as of January 2023.
The arrhythmias occurred during effort tests, extravehicular activities (EVAs), lower body negative pressure sessions, and throughout the entire mission. These included two consecutive PVCs in one astronaut during exercise and an episode of atrioventricular dissociation preceded by sinus bradycardia in two astronauts.
Junctional ectopic tachycardia (JET) is a rare syndrome of the heart that manifests in patients recovering from heart surgery. [1] It is characterized by cardiac arrhythmia, or irregular beating of the heart, caused by abnormal conduction from or through the atrioventricular node (AV node).
The combination of an accessory pathway that causes pre-excitation with arrhythmias is known as Wolff–Parkinson–White syndrome. [ 2 ] Accessory pathways are often diagnosed using an electrocardiogram, but characterisation and location of the pathway may require an electrophysiological study .
Proarrhythmia is a new or more frequent occurrence of pre-existing arrhythmias, paradoxically precipitated by antiarrhythmic therapy, which means it is a side effect associated with the administration of some existing antiarrhythmic drugs, as well as drugs for other indications. In other words, it is a tendency of antiarrhythmic drugs to ...
Both arrhythmias have at least 3 different P-wave morphologies in a single ECG lead, but the heart rate is different. When the heart rate is lower than 100 beats per minute, the heart rhythm is considered wandering atrial pacemaker. When the heart rate is greater than 100 beats per minute, the heart rhythm is considered multifocal atrial ...
A 2011 retrospective cohort study using demographic and autopsy data for a 10-year period comprising 15.2 million person-years of active surveillance suggested that prevention of sudden death in young adults should focus on evaluation for causes known to be associated with SCD (e.g., primary arrhythmia) among those under 35 years old, and ...
