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.
Dopamine, sold under the brand name Intropin among others, is a medication most commonly used in the treatment of very low blood pressure, a slow heart rate that is causing symptoms, and, if epinephrine is not available, cardiac arrest. [4] In newborn babies it continues to be the preferred treatment for very low blood pressure. [5]
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.
A low resting heart rate in the 50s is generally associated with better cardiovascular health, continues Dr. Steinbaum. ... If your heart rate is excessively high or is accompanied by other ...
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 ...
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.
Degeneration of heart tissue because of aging; Damage to tissues in the heart from heart attack, heart disease or injury; High blood pressure or hypertension; Congenital heart defect which is a permanent disorder present at birth; Heart tissue infection also known as myocarditis -Complication of heart surgery; Hypothyroidism or an underactive ...
