    “If your heart rate is low and you’re feeling dizzy, you feel like you can’t get up and exert yourself, you’ve passed out or feel like you’re going to pass out—those are symptoms that ...

  3. Bradycardia - Wikipedia

    en.wikipedia.org/wiki/Bradycardia

    Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.

  4. Sinus bradycardia - Wikipedia

    en.wikipedia.org/wiki/Sinus_bradycardia

    The decreased heart rate can cause a decreased cardiac output resulting in symptoms such as lightheadedness, dizziness, hypotension, vertigo, and syncope. [3] The slow heart rate may also lead to atrial, junctional, or ventricular ectopic rhythms. Bradycardia is not necessarily problematic.

    However, oftentimes lower heart rates can be totally normal, and a well-trained athlete can have a normal heart rate in the 50s or as low as 40 without any cause for concern, he notes.

  6. Neurogenic shock - Wikipedia

    en.wikipedia.org/wiki/Neurogenic_shock

    Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.

    This is suggested by an inappropriately low heart rate in the setting of hypotension. [3] Cardiac contusion and infarctions can result in cardiogenic shock. [3] Finally, other causes should be considered that are not related to trauma or blood loss. In the undifferentiated patient with shock, septic shock and toxic causes are also on the ...

    en.wikipedia.org/wiki/Pacemaker_syndrome

    [1] [3] In general, the symptoms of the syndrome are a combination of decreased cardiac output, loss of atrial contribution to ventricular filling, loss of total peripheral resistance response, and nonphysiologic pressure waves. [2] [4] [5] Individuals with a low heart rate prior to pacemaker implantation are more at risk of developing ...
