heart, section, the middle, heart, vf, ventricular fibrillation, vf, severely abnormal heart rhythm, arrhythmia, death, vf is responsible, 75% to 85% of sudden deaths in persons, heart problems, to pump blood out, all areas, the heart, squeeze, contract, in an organized, synchronic manner, heart's upper chambers, atria, contract, heart's bottom two chambers, ventricles, contract, vf, ventricles contract independently, the atria, areas, the ventricles contract others, relaxing, disorganized manner, most common cause of vf, heart attack, vf, occur whenever the heart muscle, a poor supply of oxygen, by specific heart disorders, lead to vf, acute, previous heart attack, ischemia, lack of oxygen, heart muscle, narrowed coronary arteries, shock, congenital heart disease, heart surgery, the heart muscle, cardiomyopathies, electrocution accidents, accidents involving direct trauma, heart, ventricular fibrillation, main cause of sudden cardiac death, in turn affects nearly 300,000 people each year, most people suffering from vf have no previous history of heart disease, many have risk factors, cardiovascular disease, smoking, hypertension, diabetes, person having vf suddenly collapses, falls unconscious, the brain, muscles have stopped receiving blood, heart, one hour, the collapse, sudden death from vf, complain of symptoms chest pain, palpitation, shortness of breath, dizziness, nausea, unresponsive, carotid pulse, in the neck, femoral pulse, in the groin hard, impossible to detect, listening, heart, a stethoscope, heartbeats cannot be heard, have varying intensity, very irregular, person having vf was already, in the hospital, paramedics have connected the person to a cardiac monitor, monitor, a disorganized arrhythmia, vf, vf in turn, evolve into a flat line, cardiac arrest, ventricular fibrillation, medical emergency, treated immediately to preserve life, whether the person having vf suddenly falls unconscious at home, street, person, in the hospital, vf is diagnosed, a cardiac monitoring station, indispensable to initiate immediate cardiopulmonary resuscitation, cpr, vf occurs, in the hospital, prompt medical attention, more likely to be successful, an out-of-hospital cardiac arrest, emergency help, help arrives, position the unconscious person's head, neck in line, the rest, the body to help the person breathe, carotid arteries, located at each side, the neck, below each angle, the jaw, place fingertips on one, the carotid arteries to try to find a pulse, not finding a carotid pulse after several attempts, sign that no pulse is present, start cpr, mouth-to-mouth breathing, chest compressions, continue cpr, person regains consciousness, help arrives, paramedics, quickly examine the person continuing cpr, vf is treated by using an external defibrillator, delivers a quick electric shock, the chest, electrical shock, convert the vf into a normal rhythm, stabilizing the heart rhythm, function, require medicines, a vein, once the vf has been converted to normal heart rhythm, patient has been transferred, hospital, resuscitated, in the street, prevent further episodes of vf, cardiologist, look, potential causes, the arrhythmia, most commonly involved, ischemic heart disease, cardiomyopathies, victims of vf, never convert, normal rhythm, die, a few minutes, a few days, the vf, from cardiac failure, vf complications, out-of-hospital cardiac arrest, survival rates of vf, slim, range between 2%, 25%, survived an episode of vf, prone to have another episode, evaluated, electrophysiologist, currently, many vf survivors, offered therapy, an implantable cardioverter defibrillator, icd, a device that is similar to a pacemaker, electrically treat new episodes of vf, they occur, icd has shown to effectively, prevent sudden cardiac death, most common complication of vf is sudden death, death, 1 hour, the onset of symptoms, followed by death, in the hospital, among people who were transferred to a hospital after rescued at home, street, workplace, survivors of vf, complications include coma, reduced mental acuity, neurological problems similar to those seen after a stroke, neurological status of patients, coma after resuscitation from out-of-hospital cardiac arrest, apparently be improved, the use, hospital, moderate hypothermia, low body temperature, someone is having vf, paramedics should, at 911, after surviving an episode of vf, informed, so that cardiac treatment, prevention, coordinated, patients, had an episode of vf, prevent further vf episodes, an icd, patients, more advisable to initiate preventive therapy, antiarrhythmic drugs, ischemic heart disease offered treatment aimed, restore normal oxygenation, heart muscle, preventing fatal arrhythmias, patients, cardiomyopathies, require special procedures, cardiac transplantation, public places, casinos, commercial aircraft, equipped, automated external defibrillators, machines, individuals to keep them at home, the automated external defibrillator has proven to be life-saving, another option, individual use, defibrillator vest, a good idea, family members, friends of both vf survivors, patients, heart disease in general to take a cpr course, cpr courses, locally available, the american red cross, hospitals, american heart association.
