55 Possible Causes for Cardiac Signs and Symptoms, Inverted P Wave

  • 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[] These include: Electrocardiogram (EKG/ECG) Holter monitor Cardiac event monitor Electrophysiology (EP) study Many clinical conditions may have similar signs and symptoms.[] 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[] Like HCM, it can cause sudden cardiac arrest in young athletes. What are the signs and symptoms? Some people who have cardiomyopathy never have signs or symptoms.[] Signs and symptoms Signs and symptoms of HCM can include the following: Sudden cardiac death (the most devastating presenting manifestation) Dyspnea (the most common presenting[]

  • Atrial Bigeminy

    P wave with a PRI 120ms.[] This is visible on the ECG as an inverted P wave (“ retrograde P wave “), usually occurring after the QRS complex.[] 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[]

  • 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[] 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[] However, the P wave is different from the sinus P waves.[]

  • Cardiac Pacemaker Insertion

    The three main signs and symptoms of cardiac tamponade: muffled heart sounds, jugular venous distention, and narrowing pulse pressure.[] Heart Failure What are signs and symptoms of cardiac tamponade? 1. Muffled heart sounds 2. Distention of the jugular vein 3. Narrowing pulse pressure 4.[]

  • Anomalies of Coronary Artery Origin

    For others, the first sign of the problem is sudden cardiac arrest, most often as a teenager or young adult while engaged in or just after vigorous exercise.[] The treatment recommendations are based on the coronary artery course, symptoms or signs concerning for decreased blood flow to the heart, and your child’s estimated risk[] […] of sudden cardiac arrest.[]

  • Patent Foramen Ovale

    Symptoms of Patent Foramen Ovale or Atrial Septal Defects Most people with patent foramen ovale or small atrial septal defects have no symptoms or signs of a defect.[] Besides a stroke, blood traveling between the atrial chambers of the heart may cause symptoms such as fatigue, shortness of breath, or cardiac rhythm abnormalities .[]

  • Atrial Arrhythmia

    Differences between how AFib and VFib feel to a person (signs and symptoms) Atrial fibrillation signs and symptoms A person with AFib may have no symptoms, but in general,[] If ventricular fibrillation isn't treated immediately, the patient will have a “sudden death” or “ cardiac arrest ” and die.[]

  • 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[…][]

  • Dextrocardia

    , aka ‘global negativity’ (inverted P wave, negative QRS, inverted T wave) Absent R-wave progression in the chest leads (dominant S waves throughout) These changes can be[] […] by, last update April 30, 2019 ECG Features of Dextrocardia Right axis deviation Positive QRS complexes (with upright P and T waves) in aVR Lead I: inversion of all complexes[] An inverted P wave in lead I is a reflection of atrial mirror reversal.[]
