  2. Bradycardia - Wikipedia

    en.wikipedia.org/wiki/Bradycardia

    A diagnosis of bradycardia in adults is based on a heart rate of less than 60 BPM, [1] although some studies use a heart rate of less than 50 BPM. [34] This is usually determined either by palpation or ECG. [1] If symptoms occur, a determining electrolytes may help determine the underlying cause. [28]

  3. Sinus bradycardia - Wikipedia

    en.wikipedia.org/wiki/Sinus_bradycardia

    Sinus bradycardia is a sinus rhythm with a reduced rate of electrical discharge from the sinoatrial node, resulting in a bradycardia, a heart rate that is lower than the normal range (60–100 beats per minute for adult humans). [1] [2]

  4. Heart rate - Wikipedia

    en.wikipedia.org/wiki/Heart_rate

    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] Bradycardia is a low heart rate, defined as below 60 bpm at rest. When a human sleeps, a heartbeat ...

  6. Reflex bradycardia - Wikipedia

    en.wikipedia.org/wiki/Reflex_bradycardia

    Reflex bradycardia is a bradycardia (decrease in heart rate) in response to the baroreceptor reflex, one of the body's homeostatic mechanisms for preventing abnormal increases in blood pressure. In the presence of high mean arterial pressure , the baroreceptor reflex produces a reflex bradycardia as a method of decreasing blood pressure by ...

    Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...

  9. Junctional rhythm - Wikipedia

    en.wikipedia.org/wiki/Junctional_rhythm

    The first finding is that junctional rhythms are regular rhythms. This means that the time interval between beats stays constant. The next normal finding is a normal QRS. Since the impulse still travels down the bundle of His, the QRS will not be wide. Junctional rhythms can present with either bradycardia, a normal heart rate, or tachycardia. [9]
