The most important cardiological diseases include myocardial infarction Heart valve defects Cardiac arrhythmia Heart failure (cardiac insufficiency) Diseases of the coronary arteries (coronary heart disease) Inflammation of the heart muscle (myocarditis) Cardiologists use various examination methods to detect such cardiological diseases. These include measuring the electrical activity of the heart (electrocardiography, ECG), cardiac catheter examinations, … Cardiology
Cardiology is a field of medicine that is particularly concerned with the study, treatment and cure of heart disease. It is therefore also referred to literally as the “study of the heart“. In order to work as a cardiologist, physicians in Germany must be able to provide evidence of special training. What is cardiology? Cardiology … Cardiology: Treatment, Effects & Risks
Interventional radiology is a relatively new subspecialty of radiology. Interventional radiology performs therapeutic tasks. What is interventional radiology? Interventional radiology is the therapeutic subspecialty of diagnostic radiology. This fact may seem quite bizarre, but it goes back to the fact that interventional radiology is still a fairly young subfield of radiology. For this reason, at … Interventional Radiology: Treatment, Effects & Risks
Summary The ECG is a simple, fast and non-invasive way to diagnose serious and life-threatening diseases. Especially cardiac arrhythmias and heart attacks can be detected easily and quickly by means of the ECG and the suspicion of these diseases always leads to the derivation of an ECG. However, since the ECG can also quickly and … Summary | Electrocardiogram
Definition/Introduction The ECG (= electrocardiogram) records the sum of the electrical voltages of all myocardial fibers and thus serves to evaluate myocardial function. In addition to the heart rhythm and heart rate, malfunctions of individual sections of the heart muscle can be detected. Every heart action is preceded by an electrical excitation, which usually begins … Electrocardiogram
Create In order to obtain a meaningful ECG, a few things must be taken into account when applying the electrodes. For better conductivity they are often moistened with water or disinfectant. As a rule, the electrodes are first applied to both forearms and both ankles; then the six chest wall electrodes are positioned. Nowadays, adhesive … Create | Electrocardiogram
ECG derivations and position types Derivations In our heart there is a permanent flow of differently charged particles (ions). This redistribution in turn generates different, electrical potentials. Through individual recordings, these “electrical heart currents” can be measured from different perspectives and levels. Combined, the recordings provide a comprehensive picture of the condition of the heart … ECG derivations and position types | Electrocardiogram
Evaluation/interpretation After recording the electrocardiogram, the doctor interprets the ECG, sometimes using a ruler standardized for this purpose. He analyzes the height of the individual deflections, the time intervals between them, as well as their duration and steepness.Thus, a correct evaluation of the ECG can make pathological processes and changes, such as infarcts or rhythm … Evaluation/interpretation | Electrocardiogram
Diagnostics of the electrocardiogram Due to the precisely defined excitation formation and regression, deviations of the individual waves and intervals can be very specifically attributed to malfunctions. By observing the individual P-waves, their regularity and frequency, conclusions about the heart rhythm are possible.A normative sinus rhythm is present if the P-waves are regular and positive … Diagnostics of the electrocardiogram | Electrocardiogram
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
Pulmonary valve regurgitation is a relatively rare condition of the heart valve, which is usually a symptom of disease. In very few cases, pulmonary valve regurgitation requires therapy; however, in severe disease, surgery is possible, so a heart valve replacement is needed. What is pulmonary valve regurgitation? Doctors speak of pulmonary valve insufficiency when the … Pulmonary Valve Regurgitation: Causes, Symptoms & Treatment
The word “cardiology” is derived from the Greek and means “the teaching of the heart“. This medical discipline is concerned with the study of the human heart in its natural (physiological) and pathological (pathological) state and function, as well as the diagnosis and treatment of heart disease. There are numerous overlaps between cardiology and other … Cardiology
