Atrial flutter is usually well-tolerated initially (a high heart rate is, for most people just a normal response to exercise); however, people with other underlying heart diseases (such as coronary artery disease) or poor exercise tolerance may rapidly develop symptoms, such as shortness of breath, chest pain, lightheadedness or dizziness ...
Holiday heart syndrome, also known as alcohol-induced atrial arrhythmias, is a syndrome defined by an irregular heartbeat and palpitations [1] associated with high levels of ethanol consumption. [2] Holiday heart syndrome was discovered in 1978 when Philip Ettinger discovered the connection between arrhythmia and alcohol consumption. [ 3 ]
Symptomatic episodes may involve heart palpitations, fainting, lightheadedness, loss of consciousness, shortness of breath, or chest pain. [2] Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14]
Dr. Patwa says that heart palpitations are tied to the heart's electrical conduction system, a network of muscle cells in the heart’s wall that control heartbeats’ rate and rhythm. “The ...
Feb. 13—Sweating, nausea, dizziness and unusual fatigue may not sound like typical heart attack symptoms. However, they are common for women and may occur more often when resting or asleep.
[1] [5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle swelling) and/or symptoms related to the tachycardia or arrhythmia (e.g. palpitations). [ 1 ] [ 2 ] Though atrial fibrillation is the most common cause of TIC, several tachycardias and arrhythmias have been associated with the disease.
"A normal heart rate is 60 to 100 beats a minute when you’re at rest," reads the Cleveland Clinic website. "Atrial flutter can make your heart’s upper chambers beat 250 to 350 times a minute.
Ventricular flutter is an arrhythmia, more specifically a tachycardia affecting the ventricles with a rate over 250-350 beats/min, and one of the most indiscernible. It is characterized on the ECG by a sinusoidal waveform without clear definition of the QRS and T waves.
