Atrial Bigeminy


Presentation

  • We report the case of a 22-year-old woman with no prior cardiac disease presenting with exercise intolerance since several months. No apparent heart disease other than a spontaneous conducted atrial bigeminy with a short coupling interval was found.[ncbi.nlm.nih.gov]
  • In this report, electrophysiologic studies on five patients with fixed coupled atrial bigeminy, identical impulse intervals arriving at the His bundle and alternating bundle branch aberrancy are presented.[ncbi.nlm.nih.gov]
  • Strengths with possible “problems expected at birth with advice on how to manage them are presented. Logical outline of management.[books.google.com]
  • BACKGROUND: Blocked atrial bigeminy (BAB) and second-degree atrioventricular block with 2:1 conduction block (2:1 AVB) both present as ventricular bradycardia and can be difficult to distinguish by echocardiography.[ncbi.nlm.nih.gov]

Arm Pain
  • If palpitations last more than 30 minutes, are becoming more frequent, or are accompanied by loss of consciousness, feeling faint, breathlessness, chest, jaw, shoulder or arm pain it would be considered appropriate to consider getting medical care immediately[healthcentral.com]

Heart Disease
  • No apparent heart disease other than a spontaneous conducted atrial bigeminy with a short coupling interval was found.[ncbi.nlm.nih.gov]

  • No further cardiac investigations are indicated as most people with this rhythm do not have organic heart disease (although in those with heart disease, it seen).[ecgclass.co.uk]
  • Most people with PACs do not have organic heart disease, although PACs are more common in patients with heart disease than in those without.[journals.lww.com]

  • Ventricular ectopics, and so ventricular bigeminy, originate from an abnormal focus within the ventricle wall. Conduction through the ventricle is not rapid via the Bundle of His, and is therefore slowed down giving a wide QRS complex.[ecgclass.co.uk]
  • The patient is in Ventricular Bigeminy. Bigeminy comes for the latin for ‘twins’. On an ECG strip, it presents as a sinus beat with a premature ventricular complex immediately following.[resus.com.au]
  • Ventricular bigeminy, the most common type of bigeminy involving ectopic firing, usually requires treatment with suppressive drugs.[ncbi.nlm.nih.gov]
Skipped Beats
  • Many patients describe them as skipped beats, because when they check their pulse, they don’t feel anything for a moment. However, your heart is not actually skipping or missing a 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]
  • You’ll feel a “skipped beat” if a premature contraction occurs before your ventricles have filled with blood. The premature beat may feel different from a normal heartbeat because little or no blood is being pumped out of your heart.[healthline.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]
Irregular Heart Rhythm
  • Frequent premature beats can also be perceived as having an irregular heart rhythm (despite the underlying sinus rhythm).[ecgwaves.com]
Denial
  • These latter cause the most problems due to denial (it is fascinating to watch this process at work, first there is denial of use, then there is denial that there could be a relationship. I will address this in another column).[healthcentral.com]

Workup

  • We all weill have some of this happen from time to time throughout our lives, but this is excessive and you deserve a better, more thoroug workup by a subspecialist who may well be able to resolve this for you or at least make it much more tolerable.[doctorslounge.com]

Inverted P Wave
  • However, every other beat has inverted P-waves in those leads. Seems like sinus rhythm with frequent PACs with some left atrial enlargement.[app.figure1.com]
  • PACS arising close to the AV node (“low atrial” ectopics) activate the atria retrogradely, producing an inverted P wave with a relatively short PR interval 120 ms (PR interval 120 ms is classified as a PJC).[litfl.com]
  • This is visible on the ECG as an inverted P wave (“ retrograde P wave “), usually occurring after the QRS complex.[lifeinthefastlane.com]

Treatment

  • In one patient there was spontaneous resolution and one patient refused treatment. This variant of the "tachy-brady" syndrome can be successfully treated by suppression of abnormal atrial impulse formation without recourse to pacemaker implantation.[ncbi.nlm.nih.gov]
  • Continued Treatment Your doctor will address any issue, such as an electrolyte imbalance or overactive thyroid , that could be causing the bigeminy.[webmd.com]

Prognosis

  • Making a correct diagnosis has important clinical implications, as their prognosis and management differ markedly.[ncbi.nlm.nih.gov]
  • Since the prognosis and clinical management of these rhythms are different, an accurate diagnosis is essential. OBJECTIVE: To identify magnetic and mechanical heart rate and rhythm parameters that could reliably distinguish BAB from 2:1 AVB.[ncbi.nlm.nih.gov]
  • Since the prognosis and clinical management of these rhythms are different, an accurate diagnosis is essential. Objective To identify magnetic and mechanical heart rate and rhythm parameters that could reliably distinguish BAB from 2:1 AVB.[scholars.northwestern.edu]
  • However, structural heart disease and poor left ventricular function are the key factors in determining the need for treatment and assessing the prognosis. [7] , [8] In our case, we have taken extreme caution in administering pharmacological agents for[karnatakaanaesthj.org]

Etiology

  • 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]
  • 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]
  • 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]

Prevention

  • Still, some lifestyle changes can prevent your PVCs from getting worse or more frequent. Since anxiety can cause your heartbeat to speed up or be abnormal, find a way to reduce your stress .[webmd.com]
  • […] deserves mention because this dysrhythmia is the most common cause of an unexpected atrial pause. 3 The pause results from the relatively early occurrence of the premature atrial contraction (PAC) during a time when the AV node is still refractory, thus preventing[journals.lww.com]
  • In large trials, the medicines have been shown to be as effective or more effective than warfarin at preventing strokes and deaths. They also have a similar or lower rate of major bleeding.[nhs.uk]
  • In conclusion, thorough history, clinical examination, and judicious use of antiarrhythmic agents recommended during pregnancy can prevent an asymptomatic ventricular ectopy transforming into a fatal arrhythmia in managing a case of ventricular bigeminy[karnatakaanaesthj.org]
