What is ventricular fibrillation? Ventricular fibrillation, or ventricular fibrillation for short, is a rhythm disorder that originates in the heart chambers. Normally, the muscle cells of the heart chambers contract 60 to 80 times per minute. During this process, blood collected in the ventricles is pumped into the systemic circulation by a coordinated contraction of … Ventricular fibrillation: Symptoms and resuscitation
The pacemakers, which brought a great progress in the treatment of diseases of the heart, help many patients to have a better quality of life and live longer. What is a pacemaker? A pacemaker or heart stimulates the heart muscle at regular intervals using electrical impulses. Cardiac arrhythmias and conduction abnormalities can be treated with … Cardiac Pacemaker: Applications & Health Benefits
Cardiac rhythm is the complete repetitive sequence of heartbeats, including electrical excitation and heart muscle contractions. In people with healthy cardiovascular systems, the atria contract first, pumping blood into the ventricles, which then contract, pushing their blood into the great systemic circulation and into the pulmonary circulation. Normally, the complete heartbeat sequences move in a … Heart Rhythm: Function, Tasks, Role & Diseases
People affected by Wolff-Parkinson-White syndrome (WPW syndrome for short) suffer from a usually non-life-threatening heart defect. Due to an additional conduction pathway for electrical impulses controlling cardiac function, tachycardia occurs. Tachycardia in young adults is often a sign that Wolff-Parkinson-White syndrome is present. What is Wolff-Parkinson-White syndrome? In Wolff-Parkinson-White syndrome, the heart rate disorder is … Wolff-Parkinson-White Syndrome: Causes, Symptoms & Treatment
Introduction A defibrillator is a device used in acute and emergency medicine, which is designed to stop the heart by means of a directed current surge. Contrary to what is often assumed, the defibrillator only leads to heart stimulation in a secondary way. The defibrillator is used when a patient is in life-threatening ventricular fibrillation. … Defibrillator
What’s an AED? AED stands for “Automated External Defibrillator“. The Automated External Defibrillator (AED) is a small, state-of-the-art device that allows fully automatic operation and is used in the treatment of life-threatening cardiac arrhythmias, such as ventricular fibrillation or ventricular flutter. 85% of all sudden cardiac deaths are caused by ventricular fibrillation or ventricular flutter. … What’s an AED? | Defibrillator
Refractory period is the phase during which re-excitation of neurons is not possible after the arrival of an action potential. These refractory periods prevent retrograde propagation of excitation in the human body. In cardiology, a disturbance of the refractory period is present, for example, in phenomena such as ventricular fibrillation. What is refractory period? The … Refractory Period: Function, Tasks, Role & Diseases
Classification The human heart usually beats 60 to 100 times per minute. If the heart beats less than 60 times per minute, this is called bradycardia. This can occur, for example, in competitive athletes, where it has no disease value, or in heart disease. If there is an acceleration of the heartbeat so that the … Cardiac arrhythmias Classification
Coronary angiography is an invasive examination of the heart vessels for diagnostic or therapeutic purposes. It is also referred to as coronary artery examination. Coronary angiography has the highest significance and informative value in all arteriosclerotic changes of the coronary vessels. What is coronary angiography? Coronary angiography is an invasive examination of the heart vessels … Coronary Angiography: Treatment, Effects & Risks
Cardiac arrhythmia (medical term: arrhythmia) is an irregular beating of the heart. Cardiac arrhythmia can vary greatly in form and duration. Most cardiac arrhythmias are harmless and occur in many people, often without them noticing the heartbeat that has gone out of beat. However, it is possible that cardiac arrhythmias last for a long time … Cardiac arrhythmias Consequences
Therapy Depending on the form and severity of the disease which is responsible for the cardiac arrhythmia, a therapy is necessary. In many cases, however, no therapy is necessary. Nevertheless, it is advisable to consult a physician who can give the all-clear if necessary in the case of recurring cardiac arrhythmias, which are perceived, for … Therapy | Cardiac arrhythmias Consequences
Various medical devices play a central role in the therapy of heart diseases and at the same time in the context of life-saving measures. In this context, the so-called defibrillators occupy a special group. What is a defibrillator? A defibrillator is a medical device for defibrillation. It can terminate cardiac arrhythmias such as ventricular fibrillation … Defibrillator: Applications & Health Benefits
