This is complemented by gastro-coronary reflexes [12] whereby the coronary arteries constrict with "functional cardiovascular symptoms" similar to chest-pain on the left side and radiation to the left shoulder, dyspnea, sweating, up to angina pectoris-like attacks with extrasystoles, drop of blood pressure, and tachycardia (high heart rate) or ...
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.

A Cochrane Review concluded that although metoprolol reduces the risk of atrial fibrillation recurrence, it is unclear whether the long-term benefits outweigh the risks. [ 33 ] This medicine may cause changes in blood sugar levels or cover up signs of low blood sugar, such as a rapid pulse rate. [ 32 ]
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 ...
For the first time a new study describes the synchronized oscillations during sleep that power the brain’s glymphatic system to help remove ‘waste’ associated with neurodegenerative diseases ...
Flurazepam has abuse potential and should never be used with alcoholic beverages or any other substance that can cause drowsiness. Addictive and possibly fatal results may occur. Flurazepam users should only take this drug strictly as prescribed, and should only be taken directly before the user plans on sleeping a full night.
Bradycardia associated with signs of shock (altered mental status, hypotension, etc.) can be an early warning sign for cardiac arrest. Signs of bradycardia include fatigue, confusion, dizziness, and lightheadedness. [4] Possible causes of bradycardia include hypoxia, hypothermia, and certain medications. [2] AV block.
