Heart rate variability visualized with R-R interval changes Electrocardiogram (ECG) recording of a canine heart that illustrates beat-to-beat variability in R–R interval (top) and heart rate (bottom).
A medical monitoring device displaying a normal human heart rate. Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm).
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).
Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm.Cardiac monitoring is usually carried out using electrocardiography, which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram.

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 heart is a muscular organ found in humans and other animals.This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2]
En su cara se nota el aumento de peso y las arrugas del dolor. Sobre la chimenea de la sala de estar tiene un pequeño santuario dedicado a Lukas, a falta de una tumba apropiada. En el centro hay un tarro de madre , un frasco de arcilla con asas que los daneses, por tradición, rellenan con comida y regalan a las madres que acaban de dar a luz.
Cardiac function curve.In diagrams illustrating the Frank–Starling law of the heart, the y-axis often describes the stroke volume, stroke work, or cardiac output.The x-axis often describes end-diastolic volume, right atrial pressure, or pulmonary capillary wedge pressure.
