However, bradycardia can also result without dysfunction of the conduction system, arising secondarily to medications, including beta blockers, calcium channel blockers, antiarrythmics, and other cholinergic drugs. Excess vagus nerve activity or carotid sinus hypersensitivity are neurological causes of transient symptomatic bradycardia ...
Sinus bradycardia is commonly seen in normal healthy persons and athletes in the absence of pathophysiological diseases or conditions. [ 1 ] Different factors or etiologies could lead to the dysfunction of the sinus node, causing a malformation or prolongation of the impulse.
Symptoms such as syncope, lightheadedness, and paresthesias occur while exercising the arm on the affected side (most commonly the left). Aortic dissection (a tear in the aorta) and cardiomyopathy can also result in syncope. [23] Various medications, such as beta blockers, may cause bradycardia induced syncope. [21]
A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia. [2] Some types of arrhythmias have no symptoms. [1] Symptoms, when present, may include palpitations or feeling a pause between heartbeats. [1]
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs by fluid ...
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 ...
Respiratory syncytial virus, a.k.a. RSV, is a common respiratory virus that usually causes mild, cold-like symptoms, according to the Centers for Disease Control and Prevention(CDC).
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
