	Heart Arrhythmia : by Ray Sahelian, M.D.
		Doctors who are planning to prescribe anti arrhythmia medicines to their patients for mild cases of arrhythmia should first consider recommending their patients eat cold water fish almost every day and perhaps add one to four fish oil capsules to their daily supplement regimen.
		The arrhythmia induced by adrenalin in rabbits was antagonized by Daidzein and it could obviously inhibit the action potential amplitude of isolated sciatic nerves in toads.
		In the anaesthetized rat, the RST extract reduced arrhythmia and infarct size induced by myocardial ischaemia and reperfusion; the effects were similar to those of tetrandrine and verapamil.

		Arrhythmias arising in the atria are called atrial or supraventricular (above the ventricles) arrhythmias.

		Such a device, known as an implantable cardioverter defibrillator (ICD), is considered effective in fighting cardiac arrest over 90 percent of the time, an astounding success for a condition that few survived as recently as 15 years ago.
		Cardiac arrest, or sudden cardiac death (SCD), happens when a heart rhythm disturbance prevents the heart from operating properly and delivering blood to the brain and other vital organs.
		Because the fibrillating heart muscle cannot contract and pump blood to the brain and vital organs, VF is the number one cause of sudden cardiac death.

	Cardiac arrhythmia
		Prerequisite to an appreciation of what cardiac arrhythmia means is an understanding of normal cardiac function and, in particular of what constitutes a normal heart rhythm.
		To summarize, cardiac arrhythmia can arise when the impulse generator (the sinoatrial node) and/or the impulse conduction system is impaired.
		Some cardiac arrhythmias which give rise to a perceived irregular heart rhythm have an adverse effect on the vital prognosis without them being perceived as being particularly unpleasant or without any significant underlying disease being found.

	Cardiac, Heart Arrhythmia
		There are several types of arrhythmias, named by the chambers of the heart in which they occur (atria or ventricles) and by what effect they have on the heart's rhythm.
		The two major types of heart arrhythmia are tachycardia (fast arrhythmia) and bradycardia (slow arrhythmia).
		Upon diagnosis, tachycardia is treated with medical therapies including anticoagulants to prevent blood clots and stroke, anti-arrhythmics to control rate and rhythm of the heart or beta-blockers to help lower blood pressure or other surgical options.

	CHIN: Transtelephonic Cardiac Event Recording for Arrhythmia Surveillance
		When a physician suspects the presence of a cardiac arrhythmia, he/she may order cardiac event recording in order to document the ECG at the time symptoms are occurring.

	\|\| DukeMedNews \|\| New Cardiac Arrhythmia Syndrome Identified
		After discovering in 2003 a mutation in a specific gene in an extended French family for the arrhythmia, the researchers have identified four other similar mutations in different families worldwide, adding further evidence that they have indeed identified a new cardiac arrhythmia syndrome.
		Patients with the ankyrin-B mutation typically have varying degrees of cardiac dysfunctions including increased risk of sudden death; however, prolonged QT intervals were not a consistent feature, indicating that this is a distinct arrhythmia, the researchers said.
		The team screened a group of 664 heart patients from the U.S. and Europe for mutations in the ankyrin-B gene and found eight patients with four new mutations, as well as the previously discovered mutation.

	The Physician and Sportsmedicine: Cardiac Arrhythmia in a Professional Football Player
		Ephedrine, through its sympathomimetic properties, is causally related to many adverse events, including cardiac arrhythmias, myocardial infarction, hypertension, cerebrovascular accidents, and death.
		Depending on where in the heart such pathology develops, the pacemaker centers may be "short-circuited," and sudden fatal arrhythmias may result.
		As in our case, reentrant arrhythmias are secondary to the adrenergic effects of ephedrine.
