50 Possible Causes for Inverted P Wave, Sinus Bradycardia

  • 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[] […] findings may include the following: ST-T wave abnormalities and LVH (common) Axis deviation (right or left) Conduction abnormalities (P-R prolongation, bundle-branch block) Sinus[] The resting ECG is unremarkable, except for sinus bradycardia and prominent U waves in some patients.[]

  • Acute Atrial Infarction

    Abstract A patient with acute right ventricular infarction who showed hyposecretion of atrial natriuretic peptide (ANP) in spite of abnormally high right atrial pressure and who died of a severe low cardiac output syndrome is reported. Right atrial infarction, which was proven at autopsy, may be responsible for[…][]

  • Atrial Bigeminy

    P wave with a PRI 120ms.[] bradycardia with ventricular rates of 38-45 beats/min and the ectopic P waves were visible on only one of the ECG channels); 3. paroxysms of atrial fibrillation initiated[] Ambulatory Holter recording ( Figure 2 ) showed periods of sinus rhythm, sinus bradycardia, ectopic atrial rhythm, and AV junctional rhythm with a mean heart rate of 52 bpm[]

  • 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.[] […] arrest with ventricular escape Sinus bradycardia Sinus bradycardia (slow heart beat) Sinus tachycardia Sinus tachycardia (fast heart beat) Summation gallop Supraventricular[] 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).[]

  • Supraventricular Tachycardia

    Inverted P waves are sometimes seen after the QRS complex. These are called retrograde p waves.[] […] arrest with ventricular escape Sinus bradycardia Sinus bradycardia (slow heart beat) Sinus tachycardia Sinus tachycardia (fast heart beat) Summation gallop Supraventricular[] A distinguishing characteristic of orthodromic AVRT can therefore be an inverted P-wave (relative to a sinus P wave) that follows each of its regular, narrow QRS complexes[]

  • 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[] When this occurs in a pattern of bigeminy, the interpreter may be fooled into thinking that sinus bradycardia is present, because every other beat is a nonconducted PAC, and[] ECG Basics: Sinus Bradycardia With A Premature Atrial Contraction This strip shows an underlying sinus bradycardia with a rate less than 40/min.[]

  • Atrial Arrhythmia

    Sinus bradycardia: The electrical signals in the sinus node are either blocked or slow down.[] […] james collier July 26, 2018 at 12:05 pm A recent EKG noted sinus Bradycardia with Sinus Arrhythmia with 2 1 ATRIOVENTRICULAR BLOCK. my doctor, treating me for underperforming[] Sinus tachycardia: The heart rate speeds up due to fast electrical signals from the sinus node.[]

  • Hypertrophic Cardiomyopathy

    New subtype of apical hypertrophic cardiomyopathy identified with nuclear magnetic resonance imaging as an underlying cause of markedly inverted T-waves.[] ECG: Findings also may include right or left axis deviation, conduction abnormalities, sinus bradycardia with ectopic atrial rhythm and atrial enlargement.[] bradycardia with ectopic atrial rhythm, and atrial enlargement.[]

  • 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[] Conclusions: Prolonged conduction, low voltage, sinus bradycardia and different atrio-ventricular or brunched blocks are classical sings of hypothyroidism, however, our case[] 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[]

  • Bradycardia

    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.An AV junctional escape is a delayed[] The pathophysiology of sinus bradycardia is dependent on the underlying cause. [1] Commonly, sinus bradycardia is an incidental finding in otherwise healthy individuals, particularly[] […] of sinus bradycardia?[]
