The apex beat (lat. ictus cordis ), also called the apical impulse, [1] is the pulse felt at the point of maximum impulse ( PMI ), which is the point on the precordium farthest outwards (laterally) and downwards (inferiorly) from the sternum at which the cardiac impulse can be felt. The cardiac impulse is the vibration resulting from the heart ...
But sometimes you may need to see a doctor. A premature ventricular contraction (PVC) is a heartbeat that starts in a different part of the heart than usual. A PVC (or lots of PVCs) can make you ...
Overview. Your pulse is the vibration of blood as your heart pumps it through your arteries. You can feel your pulse by placing your fingers over a large artery that lies close to your skin. The ...
It’s the most common arrhythmia. Atrial fibrillation, or AFib, occurs when many unstable electrical impulses misfire, causing your atria to quiver erratically. AFib causes your heart to beat ...
Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation ( i.e., the sinoatrial node ). An ectopic beat can be further classified as either a ...
A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. [1] It is necessary, but not sufficient, for normal electrical activity within the heart. [2] On the electrocardiogram (ECG), a sinus rhythm is characterised by the presence of P waves that are normal in morphology.
High blood pressure, diabetes, low blood sugar, obesity, sleep apnea, anxiety, thyroid disorders, lung disease, and autoimmune disorders are among the conditions that may cause heart rhythm ...
Torsades de pointes (French for “twisting of the points”) is one of several types of life-threatening heart rhythm disturbances. In the case of torsades de pointes (TdP), the heart’s two ...
