38 Possible Causes for Inverted P Wave, Palpitations with Skipped Beats

  • 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] Patients who have these types of rhythm abnormalities may often refer to them as palpitations, skipped beats, hard beats, irregular beats, missing beats or extra beats.[equimedcorp.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]

  • Atrial Bigeminy

    P wave with a PRI 120ms.[app.figure1.com] Patients who have these types of rhythm abnormalities may often refer to them as palpitations, skipped beats, hard beats, irregular beats, missing beats or extra beats.[equimedcorp.com] Patient may experience palpitations, skipped beats, weakness, dizziness, or CP.[ekginterpretation.tripod.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] When signs or symptoms are present, the most common ones are: Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or fast) A slow heartbeat[web.archive.org] 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] When signs or symptoms are present, the most common ones are: Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or fast) A slow heartbeat[web.archive.org] 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]

  • 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] Palpitations are feelings that your heart is skipping a beat, fluttering or beating too hard or too fast. ARVD usually affects teens or young adults.[heart.org] Symptoms includes fainting after physical activity and palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast).[marshfieldclinic.org]

  • Atrial Arrhythmia

    These are often described as hard beats, fast beats, irregular beats, skipped beats or “flip-flopping”.[docsopinion.com] They are common and may cause a wide variety of symptoms, such as a racing, skipping or fluttering sensation (called palpitations) in your chest.[hopkinsmedicine.org] The term palpitations describes an awareness of heart muscle contractions in the chest.[docsopinion.com]

  • 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[…][ncbi.nlm.nih.gov]

  • Paroxysmal Nodal Tachycardia

    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] 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] This circuit conducts down the bundle of His (resulting in a narrow QRS) and generates retrograde conduction into the atria (inverted P waves buried within the QRS).[coreem.net]

  • Premature Ventricular Contraction

    This is visible on the ECG as an inverted P wave (“ retrograde P wave “), usually occurring after the QRS complex.[lifeinthefastlane.com] When a PVC occurs as a single premature beat, patients may describe the feeling as a "palpitation" or "skipped beat."[my.clevelandclinic.org] If present, the P Waves may be positive (upright) or negative (inverted). If present, P Waves may precede, be buried in, or follow the QRS complexes haphazardly.[nurseslearning.com]

  • 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] Others experience symptoms such as: Shortness of breath Dizziness Fainting (syncope) Chest pain Feeling like the heart has skipped a beat or is somehow beating abnormally[nmihi.com] […] impulse is conducted in a retrograde fashion from the ventricles to the atria by a concealed accessory pathway orthodromic AVRT ECG : similar to orthodromic AVRT but with inverted[amboss.com]
