  2. Tachycardia - Wikipedia

    en.wikipedia.org/wiki/Tachycardia

    It may be difficult to determine the rhythm's regularity when the rate exceeds 150 beats per minute. Depending on the patient's health and other variables such as medications taken for rate control, atrial fibrillation may cause heart rates that span from 50 to 250 beats per minute (or even higher if an accessory pathway is present). However ...

  3. Sinus tachycardia - Wikipedia

    en.wikipedia.org/wiki/Sinus_tachycardia

    Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans). [1] The normal resting heart rate is 60–90 bpm in an average adult. [2]

    As its name suggests, your resting heart rate, or pulse, is the number of times your heart beats per minute when you’re at rest. (Not to be confused with blood pressure , the force with which ...

    It is usually equal or close to the pulse rate measured at any peripheral point. [2] The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 bpm. [3] Tachycardia is a high heart rate, defined as above 100 bpm at rest. [4]

  8. Hyperdynamic circulation - Wikipedia

    en.wikipedia.org/wiki/Hyperdynamic_circulation

    Hyperdynamic circulation is abnormally increased circulatory volume. Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, presenting usually with a collapsing pulse, but sometimes a bounding pulse.

  9. Tachycardia-dependent bundle branch block - Wikipedia

    en.wikipedia.org/wiki/Tachycardia-dependent...

    For example, certain situations of excessive or reduced heart rate (tachycardia or bradycardia, respectively) can cause a BBB known as a rate-dependent bundle branch block (RDBBB). This manifests in a similar fashion to a regular bundle branch block, but occurs only under conditions that affect contractile rate.
