  2. Alcoholic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Alcoholic_cardiomyopathy

    Another potential complication of alcoholic cardiomyopathy is the development of arrhythmias, or abnormal heart rhythms. [7] These irregular heart rhythms can range from mild to severe and may cause symptoms such as palpitations, lightheadedness, or even loss of consciousness. [7]

  3. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    Rhythms produced by an ectopic focus in the atria, or by the atrioventricular node, are the least dangerous dysrhythmias; but they can still produce a decrease in the heart's pumping efficiency because the signal reaches the various parts of the heart muscle with different timing than usual and can be responsible for poorly coordinated contraction.

  4. Junctional ectopic tachycardia - Wikipedia

    en.wikipedia.org/wiki/Junctional_Ectopic_Tachycardia

    Junctional ectopic tachycardia (JET) is a rare syndrome of the heart that manifests in patients recovering from heart surgery. [1] It is characterized by cardiac arrhythmia, or irregular beating of the heart, caused by abnormal conduction from or through the atrioventricular node (AV node).

  5. Tachycardia-induced cardiomyopathy - Wikipedia

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

    People with TIC most often present with symptoms of congestive heart failure and/or symptoms related to their irregular heart rhythm. [1] Symptoms of congestive heart failure can include shortness of breath, ankle swelling, fatigue, and weight gain. [2] Symptoms of an irregular heart rhythm can include palpitations and chest discomfort. [2]

  6. Rhythm interpretation - Wikipedia

    en.wikipedia.org/wiki/Rhythm_interpretation

    Rhythm interpretation is an important part of healthcare in Emergency Medical Services . Trained medical personnel can determine different treatment options based on the cardiac rhythm of a patient. There are many common heart rhythms that are part of a few different categories, sinus arrhythmia, atrial arrhythmia, ventricular arrhythmia.

  7. Junctional rhythm - Wikipedia

    en.wikipedia.org/wiki/Junctional_rhythm

    The first finding is that junctional rhythms are regular rhythms. This means that the time interval between beats stays constant. The next normal finding is a normal QRS. Since the impulse still travels down the bundle of His, the QRS will not be wide. Junctional rhythms can present with either bradycardia, a normal heart rate, or tachycardia. [9]

  8. Premature heart beat - Wikipedia

    en.wikipedia.org/wiki/Premature_heart_beat

    A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. 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 ...

  9. Atrial tachycardia - Wikipedia

    en.wikipedia.org/wiki/Atrial_tachycardia

    Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.
