Create | 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 | 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 | 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 | 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

Summary | Electrocardiogram

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

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

AV block

Atrioventricular block Bradycardic arrhythmia Definition In AV block, the electrical excitation of the sinus node is only delayed (1st degree AV block), only partially (2nd degree) or not at all (3rd degree) passed on to the chamber muscles by the AV node or subordinate structures. This means that the flow of electrical potentials is interrupted … AV block

Causes | AV block

Causes An AV block is usually caused by pathological changes in the stimulus conduction system. CHD (coronary heart disease), a heart attack and medication can lead to an AV block. It usually occurs in older people. Diagnosis of the AV block by ECG The diagnosis is made on the basis of the medical history and … Causes | AV block

AV node

Anatomy The AV node, like the sinus node, is located in the right atrium. However, it lies further down, more precisely at the transition to the right ventricle and thus in Koch’s triangle. Just like the sinus node, the AV node does not consist of nerve cells, but of specialized heart muscle cells that have … AV node
