• Skipped Beats

  Because of reduced blood being pumped, it may feel like you have skipped a beat, but you have not, although the beat was certainly not as effective as a normal beat. [equimedcorp.com]

  Symptoms of arrhythmias include Fast or slow heart beat Skipping beats Lightheadedness or dizziness Chest pain Shortness of breath Sweating Your doctor can run tests to find out if you have an arrhythmia. [icdlist.com]

  These may be mild, or they may make you feel acutely aware of how your heart is beating every moment. If you have bigeminy, you may feel that your heart is beating too fast or that your heart is skipping a beat. [healthline.com]

  Bigeminy is the alternation between a regular heartbeat and extra, skipped heartbeat. People may experience bigeminy as heart palpitations or fluttering. They may describe the sensation as the heart skipping a beat. [medicalnewstoday.com]

  Patient may experience palpitations, skipped beats, weakness, dizziness, or CP. Interventions When A-flutter is present with a 2:1 conduction, it may be difficult to differentiate the dysrhythmia from ST, PSVT, etc. [ekginterpretation.tripod.com]

  For example, in ventricular bigeminy, a sinus beat is shortly followed by a premature ventricular contraction (PVC), a pause, another normal beat, and then another PVC.[1] In atrial bigeminy, the other "twin" is a premature atrial contraction (PAC). [en.wikipedia.org]

Such is the case in the Figure, in which the key clue to the etiology of this bigeminal rhythm lies with inspection of the T wave of beat No. 1 on the tracing. [ahcmedia.com]

Distinguishing between early-occurring wide beats that are ventricular in etiology (ie, PVCs ) vs PACs that are wide because of aberrant conduction is at times a challenging task! [ecg-interpretation.blogspot.com]

This then allows for re-entrant circuits and sets up the ventricle for another PVC after the next sinus beat.[2] The constant interval between the sinus beat and PVC suggests a reentrant etiology rather than spontaneous automaticity of the ventricle.[ [en.wikipedia.org]
