Cardiac arrhythmia

•  Artificial pacemaker

  A pacemaker (or artificial pacemaker, so as not to be confused with the heart's natural pacemaker) is a medical device which uses electrical impulses, delivered by electrodes contacting the heart muscles, to regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequate heart rate, either because the heart's native pacemaker is not fast enough, or there is a block in the heart's electrical conduction system.

•  Defibrillation

  Defibrillation is the definitive treatment for the life-threatening cardiac arrhythmias, ventricular fibrillation and pulseless ventricular tachycardia. Defibrillation consists of delivering a therapeutic dose of electrical energy to the affected heart with a device called a defibrillator. This depolarizes a critical mass of the heart muscle, terminates the arrhythmia, and allows normal sinus rhythm to be reestablished by the body's natural pacemaker, in the sinoatrial node of the heart.

•  Brugada syndrome

  The Brugada syndrome is a genetic disease that is characterised by abnormal electrocardiogram (ECG) findings and an increased risk of sudden cardiac death. It is also known as Sudden Unexpected Death Syndrome (SUDS), and is the most common cause of sudden death in young men without known underlying cardiac disease in Thailand and Laos.

•  Ventricular fibrillation

  Ventricular fibrillation (V-fib or VF) is a condition in which there is uncoordinated contraction of the cardiac muscle of the ventricles in the heart, making them quiver rather than contract properly. While there is activity, perhaps best described as "writhing like a can filled with worms" it is undetectable by palpation (feeling) at major pulse points of the carotid and femoral arteries especially by the lay person. Such an arrhythmia is only confirmed by ECG/EKG.

•  Cardiac pacemaker

  The cells that create these rhythmical impulses are called pacemaker cells, and they directly control the heart rate. Artificial devices also called pacemakers can be used after damage to the body's intrinsic conduction system to produce these impulses synthetically.

•  Refractory period (physiology)

  In physiology, a refractory period is a period of time during which an organ or cell is incapable of repeating a particular action, or (more precisely) the amount of time it takes for an excitable membrane to be ready for a second stimulus once it returns to its resting state following an excitation. It most commonly refers to electrically excitable muscle cells or neurons.

•  Automated external defibrillator

  An automated external defibrillator or AED is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient, and is able to treat them through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm.

•  Ventricular action potential

  At rest, the ventricular myocyte membrane potential is about -90 mV, which is close to the potassium reversal potential. When an action potential is generated, the membrane potential rises above this level in four distinct phases. The beginning of the action potential, phase 1, specialized membrane proteins in the cell membrane selectively allow sodium ions to enter the cell. This causes the membrane potential to rise at a rate of about 300 V/s.

•  Long QT syndrome

  The long QT syndrome (LQTS) is a rare inborn heart condition in which delayed repolarization of the heart following a heartbeat increases the risk of episodes of torsade de pointes. These episodes may lead to palpitations, fainting and sudden death due to ventricular fibrillation. Episodes may be provoked by various stimuli, depending on the subtype of the condition.

•  Wolff-Parkinson-White syndrome

  Wolff-Parkinson-White syndrome (WPW) is a syndrome of pre-excitation of the ventricles of the heart due to an accessory pathway known as the bundle of Kent. This accessory pathway is an abnormal electrical communication from the atria to the ventricles. WPW is a type of atrioventricular reentrant tachycardia. The incidence of WPW syndrome is between 0.9% and 3% of the general population.
