Brugada syndrome is diagnosed by identifying characteristic patterns on an electrocardiogram. [14] The pattern seen on the ECG includes ST elevation in leads V 1-V 3 with a right bundle branch block (RBBB) appearance. There may be evidence of a slowing of electrical conduction within the heart, as shown by a prolonged PR interval.
ECG pattern in Brugada syndrome. According to recent consensus document (ref 13), type 1 ST segment elevation either spontaneously present or induced with Ajmaline/Flecainide test is considered diagnostic. Type 1 and 2 may lead to suspicion but drug challenge is required for diagnosis.
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]
The criteria to diagnose a right bundle branch block on the electrocardiogram: The heart rhythm must originate above the ventricles (i.e., sinoatrial node, atria or atrioventricular node) to activate the conduction system at the correct point. The QRS duration must be more than 100 ms (incomplete block) or more than 120 ms (complete block). [9]
The syndrome gets its name from a characteristic feature seen on an electrocardiogram (ECG) – a shortening of the QT interval. It is caused by mutations in genes encoding ion channels that shorten the cardiac action potential, and appears to be inherited in an autosomal dominant pattern. [1] The condition is diagnosed using a 12-lead ECG. [2]

Jeddah to Riyadh is the fastest growing route in the top 10, with a 10% increase in capacity, year on year, to 8.7 million. The rankings were compiled by calculating the volume of airline seats ...
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 ...
