74 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.[] All patients with coronary artery disease, diabetes, syncope, and wide complex SVT were admitted.[] 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[]

  • 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[] CONCLUSION: Supraventricular tachycardia is a common dysrhythmia that can result in syncope or myocardial infarction.[] 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[]

  • 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[] 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[] The following symptomatology may be seen in patients with HCM: Dyspnea Pre-syncope or syncope Chest pain Orthopnea Dizziness Paroxysmal Nocturnal Dyspnea (PND) Palpitations[]

  • Atrial Arrhythmia

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

  • Anomalies of Coronary Artery Origin

    Keywords ALCAPA; Sudden cardiac death; Anomalous origin of the coronary arteries; Syncope; Exercise intolerance; Dyspnea; Chest pain Epidemiology Heart disease represents[] […] secondary to the tangential proximal course of the artery are some other mechanisms postulated to compromise coronary blood flow, which can manifest as angina, palpitations, syncope[] Most CAA rest asymptomatic while some show up with dyspnea on exertion, syncope during strenuous exercise, fatigue and chest pain.[]

  • 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[] They typically are not associated with chest pain, fatigue, dyspnea, or syncope.[] Repeated PACs or bigeminy may cause syncope due to low stroke volume or inadequate cardiac output. After several PACs, hypotension may occur.[]

  • 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.[] The indications of electrophysiology study were nonspecific palpitation (n 5), unexplained syncope (n 6), postablation of accessory pathways (n 4), and postmodification of[] 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).[]

  • 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[] 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[] Abstract Two patients (aged 46 and 49 years) are presented who gave a history of several years' duration of unsteadiness, dizziness, and syncopal attacks on standing.[]

  • Atrial Bigeminy

    P wave with a PRI 120ms.[] .  58 year old male Mr.Kannan, who came to hypertension OP for routine checkup No H/o chest pain, palpitation or syncope Known smoker for past 20 years – 10 cigarettes[] Pacing Modes Patient 63-year-old man with a history of paroxysmal atrial fibrillation; full right bundle branch block pattern on the electrocardiogram; 3 episodes of sudden syncope[]

  • 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[] Syncope may be the presenting symptom in these conditions. However, cocaine-induced bradyarrhythmias have been scarcely mentioned.[] He complained of syncope which followed convulsions. Their symptoms might be due to circulatory shock caused by a lazy lower pacemaker from the ventricle.[]
