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
We have become so accustomed to many medical achievements that we take their existence for granted: Artificial hip or knee joints, hearing or vision aids and also the pacemaker are normality for us today. Here you can find out exactly what a pacemaker is and when it is used. What is a pacemaker? A pacemaker … Cardiac Pacemaker: Small Device with a Big Impact
Synonyms in a broader sense Pacemaker, HSM,
Magnetic resonance imaging is often referred to as MR or MRI. In medicine, magnetic resonance imaging is a so-called imaging procedure. What is magnetic resonance imaging? Magnetic resonance imaging (MRI) is an imaging procedure. It is mostly used for diagnosis and to visualize the structure and function of tissues and organs. This means that magnetic … Magnetic Resonance Imaging: Treatment, Effects & Risks
Before implanting/operating a pacemaker, a detailed examination of the patient is both necessary and possible, as this is not an emergency operation and can therefore be well planned. It usually lasts less than an hour and can usually be performed under local anesthesia, only in a few exceptional cases a general anesthesia is necessary. The … Pacemaker surgery
Introduction Life expectancy in atrial fibrillation depends on the type of arrhythmia and the treatment options. If there is cardiac disease in addition to atrial fibrillation, life expectancy decreases compared to healthy people. However, due to the treatment options available today, life expectancy is significantly higher than it was 50 years ago. Does atrial fibrillation … What is the life expectancy in atrial fibrillation?
What can I do to positively influence my life expectancy in case of existing atrial fibrillation? In order to positively influence life expectancy in existing atrial fibrillation, two points are important: appropriate therapy and a healthy lifestyle. If the atrial fibrillation is known, a cardiologist must be visited regularly and examine the heart thoroughly. It … What can I do to positively influence my life expectancy in case of existing atrial fibrillation? | What is the life expectancy in atrial fibrillation?
Definition The sinus node (also: sinuatrial node, SA node) is the primary electrical pacemaker of the heart and is largely responsible for heart rate and excitation. Function of the sinus node The heart is a muscle that pumps on its own, which means it is not dependent on nerves like most muscles. This is because … Sinus node
Sinus node defect If the sinus node fails as the primary pacemaker and stimulation center of the heart, a secondary pacemaker must step in for it (sick sinus syndrome). This is called the atrioventricular node (AV node) and can take over the function of the sinus node to a certain extent. It generates a rhythm … Sinus node defect | Sinus node
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
Electroconvulsive therapy was invented as early as 1937 by two Italian doctors, Bini and Cerletti, to treat and alleviate mental disorders. Although this form of therapy is still used in psychiatry today, it is considered controversial even among experts. Studies have demonstrated its benefits in certain psychiatric conditions. What is electroconvulsive therapy? Electroconvulsive therapy or … Electroconvulsive Therapy: Treatment, Effects & Risks
Electroneurographic examination (electroneurography (ENG)) is a method of determining the nerve conduction velocity of peripheral nerves in neuronal and/or muscular diseases. In the majority of cases, electroneurography is unproblematic and not associated with any complications. What is electroneurography? Electroneurography is the name given to a diagnostic procedure in which the nerve conduction velocity of potentially … Electroneurography: Treatment, Effects & Risks
