66 Possible Causes for Atrial Arrhythmia, Inverted P Wave

  • Premature Atrial Contractions

    wave is abnormal Premature (earlier than expected) Morphology different than normal P wave Inverted P wave suggests atrial source near AV junction Nearly normal P waves suggest[fprmed.com] […] complexes after pulmonary vein isolation predicts recurrences of atrial arrhythmias.[link.springer.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[lifeinthefastlane.com]

  • Paroxysmal Supraventricular Tachycardia

    Most patients present with palpitations and dizziness, and their electrocardiogram demonstrates a narrow QRS complex and regular tachycardia with hidden or inverted P waves[ncbi.nlm.nih.gov] Arrhythmias include atrial arrhythmias, ventricular tachycardia, and sudden cardiac death.[ncbi.nlm.nih.gov] P waves in leads II, III, aVF, V 3 -V 6 Rare: References: [1] [3] [4] Pathophysiology AVRT Do not confuse atrioventricular reentrant (or reciprocating) tachycardia ( AVRT[amboss.com]

  • Supraventricular Tachycardia

    Inverted P waves are sometimes seen after the QRS complex. These are called retrograde p waves.[acls-algorithms.com] This is the first report in the literature of atrial arrhythmia in these cases with chest trauma.[ncbi.nlm.nih.gov] waves may be non-identifiable, especially when the ventricular rate is high If P waves are present, they will likely be inverted in leads II, III, and aVf QRS complex duration[medictests.com]

  • Patent Foramen Ovale

    The most common complications include atrial arrhythmia and bleeding. Infectious complications are exceedingly rare.[ncbi.nlm.nih.gov] The aim of the study is to assess the incidence of atrial fibrillation, supraventricular tachi-arrhythmias, and atrio-ventricular block in the acute and very long-term follow-up[ncbi.nlm.nih.gov] Atrial arrhythmias and evidence of residual shunting appear to be the most common long-term complications.[healio.com]

  • Atrial Arrhythmia

    OBJECTIVES: To determine the frequency and mechanisms of adenosine-induced atrial arrhythmias.[ncbi.nlm.nih.gov] BACKGROUND: Atrial arrhythmia remains one of the major complications in the longer term after the Fontan procedure.[ncbi.nlm.nih.gov] Thirty-nine patients (25.2%) presented with late atrial arrhythmia.[ncbi.nlm.nih.gov]

  • Acute Atrial Infarction

    Compromised atrial coronary anatomy is associated with atrial arrhythmias and atrioventricular block complicating acute myocardial infarction.[link.springer.com] Right atrial infarction, atrial arrhythmia and inferior myocardial infarction form a missed triad: a case report and review of the literature.[rpcardio.com] The presence of atrial infarction should be suspected in any case of acute myocardial infarction with any form of atrial arrhythmia.[meducator3.net]

  • Atrial Bigeminy

    P wave with a PRI 120ms.[app.figure1.com] 2 What causes atrial arrhythmias?[healthtap.com] […] with RVR and bigeminy with PAC so a lot of atrial #Arrhythmias abdu Critical Care Resident Malignant pericardial effussion[app.figure1.com]

  • Atrioventricular Junctional Rhythm

    Retrograde inverted P waves with short PR intervals and a heart rate of 94/minute denotes to accelerated junctional rhythm. Click here for a more detailed ECG ECG 3.[metealpaslan.com] Low atrial or junctional rhythm, second degree atrioventricular block, right ventricular escape beats, ventricular escape-capture bigeminy, ventriculophasic atrial arrhythmia[uthsc.pure.elsevier.com] The presence of inverted P waves indicates that the primary pacemaker has shifted to the AV node (in this case probably high in the AV node).[equimedcorp.com]

  • Ostium Primum Atrial Septal Defect

    Mild right ventricular hypertrophy Inverted P waves in Sinous Venosus type Right Bundle Branch Block is seen which is partial or complete 17.[slideshare.net] Repair is preferred in patients younger than 10 years to decrease the risk of persistent atrial arrhythmias or pulmonary vascular disease in later life.[emedicine.medscape.com] The presence of advanced age at operation, symptoms, atrial arrhythmias, mitral regurgitation or moderately increased pulmonary vascular resistance did not predict late postoperative[onlinejacc.org]

  • Atrial Tachyarrhythmia with Short PR Interval

    Diagnostic criteria include PR interval of no more than 120 ms, normal QRS complex duration, a normal or inverted P wave, and paroxysmal supraventricular tachycardia (PSVT[patient.co.uk] In this condition there are: short PR intervals and atrial arrhythmias no delta waves This occurs in the presence of a fast-conducting pathway within the atrioventricular[gpnotebook.co.uk] She was euthyroid; ECG revealed regular rhythm with inverted P waves, short PR interval, absent delta waves with normal QRS morphology ( Figure 1 ).[ncbi.nlm.nih.gov]
