Sudden cardiac death – in Germany alone, 100,000 people die this “quick” death each year. Most often, arrhythmias (ventricular fibrillation) are the reason, when the heart gets out of sync and beats so fast and disorderly that cardiovascular arrest is the result. In such a situation, only treatment with an electric shock to the heart … Early Defibrillation: Salutary Shock in Sudden Heart Failure
The resting potential is the voltage difference of -70 mV that exists between the interior and the surroundings of neurons in the nonexcited state. The potential is relevant to the formation of action potentials. Cyanide poisoning prevents restoration of the resting potential and leads to neuronal collapse. What is the resting potential? The resting potential … Resting Potential: Function, Tasks, Role & Diseases
Patients with certain underlying conditions, such as renal insufficiency or adrenal hypofunction (Addison’s disease), and patients taking diuretic medications in combination with antihypertensive agents should think about hyperkalemia and seek medical attention if they suddenly notice a furry sensation on the tongue or tingling on the skin. Cardiac arrhythmias may be the result of this … Hyperkalemia: Causes, Symptoms & Treatment
What’s asystole? The term asystole is a medical term. It describes the complete absence of electrical and mechanical action of the heart, i.e. the heart stops. Asystole is fatal within minutes if left untreated and requires immediate medical intervention. An asystole can be detected in the ECG. Clinically it is indicated by a missing pulse. … Asystole
Who needs a defibrillator? During resuscitation, only patients with ventricular fibrillation need defibrillation. Patients with asystole do not benefit from defibrillation. After a surviving cardiac arrest it is an important question whether a defibrillator should be implanted. This is important because the probability of suffering another cardiac arrest is significantly increased in patients who have … Who needs a defibrillator? | Asystole
Synonyms in a broader sense Active substance: amiodarone hydrochloride Antiarrhythmics, Action names: Cordarex® Amiogamma® Aminohexal® Cordarex® Amiogamma® Aminohexal® Cordarex® Amiogamma® Aminohexal® The active ingredient amiodarone is used in the treatment of cardiac arrhythmias and the drug is classified as a class III antiarrhythmic drug. Amiodarone can be used to help in cases of disturbed transmission … Amiodarone
Mode of action (for very interested readers) In order for large quantities of blood to circulate continuously in the body’s circulation, the heart needs to be pumped regularly. Heart muscle cells are excited at regular intervals for this purpose. The heart has its own system of impulse conduction, the excitation of the heart muscle cells … Mode of action (for very interested readers) | Amiodarone
Synonyms in the broadest sense tachycardia, electrical dissociation, cardiac arrest, defibrillator Definition ventricular fibrillation In contrast to atrial fibrillation, in ventricular fibrillation/ventricular flutter – as the name suggests – the chambers are the site of the event. In people with ventricular fibrillation and ventricular flutter, the heart rate is abnormally increased. Note: Ventricular flutter is … Ventricular flutter and ventricular fibrillation
Therapy ventricular fibrillation Acute treatment: In case of ventricular flutter and ventricular fibrillation, resuscitation by electric shock is started immediately (defibrillation). Two plate electrodes are placed on the chest. In accordance with the ECG, direct current is delivered with an energy of 50 to max. 400 joules. The doctor can immediately recognize the success or … Therapy ventricular fibrillation | Ventricular flutter and ventricular fibrillation
Tripping of the heart, heart failure, palpitations, palpitations, palpitations, Swindle Fear Nervousness or Faint (syncope) come. 2. ventricular extrasystoles (VES, ventricular extrasystoles) In ventricular extrasystole, the extrasystole develops in the tissue of the heart chambers. It is also known that these additional heartbeats are produced in the ectopic tissue. (Ectopic means that normally no electrical … Extrasystole

Extrasystole after sport In many cases, the exact temporal correlation of the occurrence of an extrasystole can already help to narrow down its possible causes. For example, a pronounced lack of sleep, or severe overtiredness, can lead to the development of an extrasystole even in an actually completely healthy person. Another particularly frequent cause of … Extrasystole after sport | Extrasystole
