  2. Atrial flutter - Wikipedia

    en.wikipedia.org/wiki/Atrial_flutter

    Atrial flutter (AFL) is a common abnormal heart rhythm that starts in the atrial chambers of the heart. [1] When it first occurs, it is usually associated with a fast heart rate and is classified as a type of supraventricular tachycardia . [ 2 ]

  3. Tachycardia-induced cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Tachycardia-induced_cardio...

    [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. [5] [1]

  4. Ventricular flutter - Wikipedia

    en.wikipedia.org/wiki/Ventricular_flutter

    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.

  5. Premature heart beat - Wikipedia

    en.wikipedia.org/wiki/Premature_heart_beat

    Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or a skipped beat. They typically have no long term complications. They most often happen naturally but may be associated with caffeine, nicotine, or ...

  6. Holiday heart syndrome - Wikipedia

    en.wikipedia.org/wiki/Holiday_heart_syndrome

    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 ]

  7. Pre-excitation syndrome - Wikipedia

    en.wikipedia.org/wiki/Pre-excitation_syndrome

    Pre-excitation may not cause any symptoms but may lead to palpitations caused by abnormal heart rhythms. It is usually diagnosed using an electrocardiogram, but may only be found during an electrophysiological study. [2] The condition may not require any treatment at all, but symptoms can be controlled using medication or catheter ablation.

  8. Right atrial enlargement - Wikipedia

    en.wikipedia.org/wiki/Right_atrial_enlargement

    Symptoms of right atrial enlargement include palpitations, dyspnea, paroxysmal tachycardia, general malaise, shortness of breath, syncope, chest pain, fatigue, cyanosis, loss of appetite, tachycardia, fever, and cough. Many patients with right atrial enlargement are asymptomatic. [8]

  9. Sinus node dysfunction - Wikipedia

    en.wikipedia.org/wiki/Sinus_node_dysfunction

    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 ...
