The Business Process Management (BPM) world acknowledges the critical importance of modeling standards for optimizing and standardizing business processes. The Business Process Model and Notation (BPMN) version 2 has brought significant improvements in event and subprocess modeling, significantly enriching the capabilities for documenting ...
The programmed delay at the AV node also provides time for blood volume to flow through the atria and fill the ventricular chambers—just before the return of the systole (contractions), ejecting the new blood volume and completing the cardiac cycle. [8] (See Wiggers diagram: "Ventricular volume" tracing (red), at "Systole" panel.)
Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide .
A business process modeling of a process with a normal flow with the Business Process Model and Notation. Business process modeling (BPM) is the action of capturing and representing processes of an enterprise (i.e. modeling them), so that the current business processes may be analyzed, applied securely and consistently, improved, and automated.
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).
where bpm stands for beats per minute. The HR is often used to compute the heart rate variability (HRV) a measure of the variability of the time interval between heartbeats. HRV is often used in the clinical field [ 6 ] to diagnose and monitor pathological conditions and their treatment, but also in the affective computing research to study new ...
An impulse (action potential) that originates from the SA node at a relative rate of 60–100 bpm is known as a normal sinus rhythm. If SA nodal impulses occur at a rate less than 60 bpm, the heart rhythm is known as sinus bradycardia. If SA nodal impulses occur at a rate exceeding 100 bpm, the consequent rapid heart rate is sinus tachycardia ...
Premature atrial contraction; Other names: Supraventricular extra systole (SVES), supraventricular ectopy (SVE) Two PACs with a compensatory pause seen on an ECG rhythm strip. A "skipped beat" occurs and rhythm resumes 2 P-to-P intervals after the last normal sinus beat.
