		The precordial thump is thought to prcduce an electrical depolarization of 2 to 5 Joules.
		The precordial thump should be delivered as soon as possible after cardiac arrest or re-arrest.
		Remember that the precordial thump is appropriate at this time, as the re-arrest will be an attendant-witnessed re-arrest.

	Precordial thump - Wikipedia, the free encyclopedia
		The precordial thump is thought to produce an electrical depolarization of 2 to 5 Joules.
		However, the thump is effective only if used at the onset of ventricular fibrillation or pulseless ventricular tachycardia and so should be used only when the arrest is witnessed or monitored.
		The use of the precordial thump technique has sometimes been shown in movies and television, usually in passing without any explanation.

	Precordial thump (via CobWeb/3.1 planetlab2.cs.unc.edu) (Site not responding. Last check: 2007-11-03)
		A precordial thump is a medical procedure used in the initial response to a witnesssed cardiac arrest when no defibrillator is immediately available.
		While the odds of success are poor, if a precordial thump is done properly little time is lost.
		The performance of a precordial thump is outside the scope of first aid and requires at minimum training in advanced cardiac life support.

		A precordial thump is a single, sharp and quick blow over the midpoint of the sternum (breastbone) delivered with the fist from about 20-30cm over the chest.
		The use of the precordial thump is restricted to the very specific circumstances of pole-top rescue in the electrical industry.
		A precordial thump may be used in some Advanced Life Support situations when the casualty is monitored on an electrocardiogram.

	Precordial examination - Wikipedia, the free encyclopedia
		In medicine, the precordial exam, also cardiac exam, is performed as part of a physical examination, or when a patient presents with chest pain suggestive of a cardiovascular pathology.
		The valve area are palpated for abnormal pulsations (known as thrills) and precordial movements (known as heaves).

		"The precordial thump is something which has found its way into our lore," said Dr. Harlan M. Krumholz, a professor of cardiology at Yale University School of Medicine who was not involved in the study.
		Among the 29 animals, the researchers were able to induce 31 cases of cardiac arrest, according to the report, which was to be presented Thursday at the Heart Rhythm Society's annual meeting in New Orleans.
		Based on our data, we cannot recommend precordial thump to cardiac arrest victims, if external defibrillation is readily available," the researchers concluded.

	eMedicine - Commotio Cordis : Article Excerpt by: Steven M Yabek, MD, FAAP, FACC
		Ventricular fibrillation can be triggered by chest wall impact immediately over the heart and occurs most frequently with impact over the center of the left ventricle.
		During the experimental studies, when precordial impacts were timed to occur during various points in the cardiac cycle, the electrophysiologic consequences were determined to be critically dependent on impact timing.
		Consistently, 90% of low-energy precordial impacts, produced by striking the precordium with a wooden object similar in size and weight to a baseball, resulted in immediate ventricular fibrillation if the impact was delivered within a 15-millisecond window that occurred 15-30 milliseconds before the T-wave peak.

	Ask the Experts
		Remember that you will have one or more other people in the car doing CPR, so ensure that the AED does not interfere with them, and that everyone knows where the cords are.
		The precordial thump is indicated for an attendant-witnessed arrest when AED is not immediately available.
		If you regain pulses and the patient subsequently re-arrests, again use the precordial thump if the AED is not immediately available.

	CPR Protocol Policy (Site not responding. Last check: 2007-11-03)
		If no pulse and patient is monitored, initiate precordial thump with closed fist to midsternal area.
		The precordial thump is to be used only on monitored patients who show a monitor pattern ventricular fibrillation or V-Tach, and/or complete heart block.
		The pulse check and thump are initiated before ventilation because in a monitored arrest the time lapse since arrest until rescue is short, the heart remains oxygenated and a thump may return the heart to a rhythm.

	MonkeyFilter \| Curious, George: Restart my heart
		The technique is called a "precordial thump" and IIRC from my EMT trainer's comments, was used before the advent of automated external defibrillators to restore normal rythms to fibrillating hearts.
		Understand that while the technique may have detrimental effects, there is evidence to suggest that you can convert someone out of ventricular rhythms.
		We learned about The Thump in our wilderness EMT class because it was better than nothing.

		This is covered somewhere in the morass that is thread on Dim Mak and "death touch," but this is a variation of the "precordial thump"--it does not take too much to impart energy to the heart.
		I used to be a Paramedic, and had been told that the thump could stop the heart.
		He told me that in addition to the precordial thump physiology, there's a nerve bundle much like the one in the brachial area, that contributes to the effectiveness of the "dim mak" that was shown.

		Sometimes the heart can be returned to normal sinus rhythm with a precordial thump.
		The patient is struck sharply on the lower sternum with a clenched fist, which is then withdrawn rapidly.
		The techniques used in advanced cardiac life support depend on the type of abnormal rhythm-that is, ventricular fibrillation, ventricular tachycardia, asystole, or electromechanical dissociation.

		If the precordial thump successfully converts the patient to a normal sinus rhythm, continue to monitor the patient.
		On a monitored patient that is pulseless, apneic, unconscious, and the AED analysis indicate that no shock is indicated, but the monitor shows the patient in ventricular tachycardia, the EMT-ADT will deliver one precordial thump.
		If the precordial thump successfully converts the VT to a pulsating rhythm, continue to monitor the patient.

		A precordial thump is advised only when a defibrillator is not available.
		A forceful precordial thump can rarely convert VF or VT to a functional cardiac rhythm, and there is no evidence of deleterious effect (eg, converting VT to VF) in the cardiac arrest setting.
		One or 2 blows can be delivered to the junction of the middle and lower third of the sternum with a clenched fist held 20 to 25 cm above the chest.

		There's some evidence that the energy of the strike can sometimes convert a ventricular tachycardia to a normal rhythm, and in the case of witnessed arrest, it's worth the risk.
