86 Possible Causes for Inverted P Wave, Syncope

  • Supraventricular Tachycardia

    Inverted P waves are sometimes seen after the QRS complex. These are called retrograde p waves.[acls-algorithms.com] Age 40 years, feeling of dizziness/syncope or chest pain associated with tachycardia, the absence of heart disease or short PR interval was more frequent in patients with[ncbi.nlm.nih.gov] Retrograde (inverted) P waves may also be seen. 5.[clinicaladvisor.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] Supraventricular tachycardia is a common dysrhythmia that can result in syncope or myocardial infarction.[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]

  • Cardiomyopathy

    There are some signs of left atrial enlargement — leftward deviation of the P wave axis (positive P waves in I and aVL, inverted in III and aVF) and prolongation of the terminal[lifeinthefastlane.com] Dogs diagnosed this way had more VPCs, polymorphic VPCs, couplets, triplets, VTs and R-on-T-phenomenon and syncope, decreased right ventricular function and dilatation in[ncbi.nlm.nih.gov] The obstructive type is also notable for signs of reduced blood flow ( dyspnea , vertigo , syncope ).[amboss.com]

  • Bradyarrhythmia

    This usually appears on an EKG with a normal QRS complex accompanied with an inverted P wave either before, during, or after the QRS complex. [3] An AV junctional escape is[en.wikipedia.org] Syncope may be the presenting symptom in these conditions. However, cocaine-induced bradyarrhythmias have been scarcely mentioned.[ncbi.nlm.nih.gov] He complained of syncope which followed convulsions. Their symptoms might be due to circulatory shock caused by a lazy lower pacemaker from the ventricle.[ncbi.nlm.nih.gov]

  • 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] We present the case of a 44-year-old methamphetamine abuser who had a 3-month history of worsening fatigue and near-syncope.[ncbi.nlm.nih.gov] Inverted inferior P waves, right-axis deviation. C, Ostium primum ASD. First-degree AV block, left-axis deviation, voltage evidence of right ventricular hypertrophy.[circ.ahajournals.org]

  • Paroxysmal Ventricular Tachycardia

    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] If there is a loss of consciousness in the supine position or the patient has no aura, then the patient should be evaluated for VT, as vasovagal syncope usually appears in[symptoma.com] Retrograde (inverted) P waves may also be seen. 5.[clinicaladvisor.com]

  • Atrial Arrhythmia

    Our case report shows that sarcoidosis can initially manifest itself as syncope with new-onset atrial arrhythmia.[ncbi.nlm.nih.gov] Reduced cardiac performance produces symptoms of faintness or syncope and leads to increased sympathetic stimulation, which may increase the heart rate further.[bmj.com] […] or near syncope respectively), despite standard prescribed treatment.[disabilitybenefitscenter.org]

  • Ventricular Arrhythmia

    Example 4 Torsades de Pointes: Sinus rhythm, or possibly ectopic atrial rhythm (biphasic / inverted P waves in lead II).[lifeinthefastlane.com] In multivariate analysis, the factors significantly associated with an increased risk of VA were syncope (p 0.007), age 55 years (p 0.008), atypical TC (p 0.04), a troponin[ncbi.nlm.nih.gov] Syncope, arrhythmia or sudden death may be the first symptom.[ncbi.nlm.nih.gov]

  • Tachyarrhythmia

    waves, fixed P-R interval: sinus tachycardia Multiform P waves, variable P-R interval: MFAT Inverted P waves: AV nodal tachycardia Sawtooth P waves: A-flutter No atrial activity[openanesthesia.org] In patients who present with more severe symptoms, such as syncope, outpatient monitoring may be insufficient.[accessmedicine.mhmedical.com] Her ECG showed regular narrow QRS complex long RP tachycardia at a rate of 186 beats per minute (bpm) with inverted p waves in lead III [Figure 1] .[ruralneuropractice.com]

  • Flecainide

    The long PR interval, 1:1 atrioventricular conduction and inverted P waves in leads II, III, and aVF consistent with permanent junctional reciprocating tachycardia are to[annalspc.com] A man presented with recurrent syncope, weakness and fatigue. His ECG showed marked QRS widening and he had gross hyponatraemia and hypokalaemia.[ncbi.nlm.nih.gov] This case report describes a 68-year-old woman presenting with flecainide induced syncope due to torsades de pointes (TP) ventricular tachycardia.[ncbi.nlm.nih.gov]
