  2. Premature atrial contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_atrial_contraction

    This can be either a premature atrial contraction or a premature impulse from the atrioventricular node. SVES should be viewed in contrast to a premature ventricular contraction that has a ventricular origin and the associated QRS change. Instead of the electrical impulse beginning in the sinoatrial (SA) node and propagating to the ...

  3. Ectopic beat - Wikipedia

    en.wikipedia.org/wiki/Ectopic_beat

    An ectopic beat can be further classified as either a premature ventricular contraction (PVC), or a premature atrial contraction (PAC). [1] Some patients describe this experience as a "flip" or a "jolt" in the chest, or a "heart hiccup", while others report dropped or missed beats.

  4. Ectopic pacemaker - Wikipedia

    en.wikipedia.org/wiki/Ectopic_pacemaker

    A premature contraction will not follow the normal signal transduction pathway, and can render the heart refractory or incapable of transmitting the normal signal from the SA node. Location of the pacemaker can also change its effect on the SA node and its rhythm. An ectopic pacemaker located in the atria is known as an atrial pacemaker and can ...

  5. 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 ...

  6. Bigeminy - Wikipedia

    en.wikipedia.org/wiki/Bigeminy

    Premature atrial contractions by contrast do not have a compensatory pause, since they reset the sinus node, but atrial or supraventricular bigeminy can occur. If the PACs are very premature, the wavefront can encounter a refractory AV node and not be conducted.

  7. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    The normal heart rate of the fetus is between 110 and 160 beats per minute. Any rhythm beyond these limits is abnormal and classed as a fetal arrhythmia. These are mainly the result of premature atrial contractions, usually give no symptoms, and have little consequence.

  8. Pre-excitation syndrome - Wikipedia

    en.wikipedia.org/wiki/Pre-excitation_syndrome

    Pre-excitation syndrome is a heart condition in which part of the cardiac ventricles are activated too early. [1] Pre-excitation is caused by an abnormal electrical connection or accessory pathway between or within the cardiac chambers.

  9. Premature ventricular contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_ventricular...

    Premature ventricular contraction in an ECG (arrows) of a dog, caused by dilated cardiomyopathy. Premature ventricular contractions occur in healthy persons of any age, but are more prevalent in the elderly and in men. [3] In a very significant proportion of people they occur spontaneously with no known cause. [citation needed]
