61 Possible Causes for Absent P Waves

  • Atrial Standstill

    Diagnostic criteria of atrial standstill Absent P waves both on surface and intracardiac ECG. Junctional bradycardia.[metealpaslan.com] Abstract A forty-five year old man with longstanding rheumatic heart disease whose surface electrocardiogram (ECG) showed absent P waves and two alternating QRS complex rhythms[ncbi.nlm.nih.gov] Electrocardiographic findings include bradycardia, ectopic supraventricular rhythms, lack of atrial excitability and absent P waves. ( Orphanet Rare Disease Ontology , Orphanet[amp.pharm.mssm.edu]

  • Hyperkalemia

    Role of inducing K loss via the GI tract in the management of hyperkalemia Setting Recommendations Hyperkalemia with severe ECG changes (e.g. absent P waves, wide QRS complex[doi.org] Example of bradycardia with absent or flattened p waves in hyperkalemia. Care of Dr. Smith’s ECG blog.[emergencymedicinecases.com] Peaked T waves. Example 5 Hyperkalaemia: Broad complex rhythm with atypical LBBB morphology. Left axis deviation. Absent P waves.[lifeinthefastlane.com]

  • Pulmonary Emphysema

    Virtually absent R waves in the right precordial leads (SV1-SV2-SV3 pattern).[lifeinthefastlane.com] Peaked P waves. Low QRS voltages (most obvious in the limb leads). Clockwise rotation (transitional lead V6).[lifeinthefastlane.com] Peaked P waves in the inferior leads 2.5 mm (P pulmonale) with a rightward P-wave axis (inverted in aVL) Clockwise rotation of the heart with a delayed R/S transition point[lifeinthefastlane.com]

  • Bradyarrhythmia

    In third-degree, or complete, SA block, the surface ECG is identical to that of sinus arrest, with absent P waves.[emedicine.com] Diagnosis is made via 12 lead EKG and will show an absent P wave, QRS wave and T wave (asystole).[lecturio.com] ECG typically shows absent P waves with escape rhythm: Junctional - narrow complexes at 45-60 bpm. Ventricular - wide complexes at 30-45 bpm. Usual causes: Ischaemia.[patient.info]

  • Atrial Arrhythmia

    waves absent; oscillating baseline f (fibrillation) waves Atrial rate 350-600 beats/min Irregular ventricular rhythm Ventricular rate 100-180 beats/min As a general rule the[bmj.com] This chaotic electrical activity results in a chaotic wave form between the QRS complexes. P waves are absent. They are replaced by lower case "f" waves.[practicalclinicalskills.com] Regular ventricular rhythm Ventricular rate typically 150 beats/min (with 2:1 atrioventricular block) 4:1 is also common (3:1 and 1:1 block uncommon) Atrial fibrillation P[bmj.com]

  • Bradycardia

    In third-degree, or complete, SA block, the surface ECG is identical to that of sinus arrest, with absent P waves.[emedicine.com] ECG typically shows absent P waves with escape rhythm: Junctional - narrow complexes at 45-60 bpm. Ventricular - wide complexes at 30-45 bpm. Usual causes: Ischaemia.[patient.info] Different P-wave morphologies PR duration variations. Not normally clinically significant.[patient.info]

  • Atrioventricular Junctional Rhythm

    P waves may be present or absent. P waves may not be related to the QRS complexes.[metealpaslan.com] How to Identify a Junctional Rhythm A junctional rhythm can be identified by having a regular R-R interval and one of the following P wave characteristics: Absent P Waves:[emtresource.com] , usually inverted or absent * PR interval: short (if P wave is in front of QRS), or "not applicable" if P wave is AFTER QRS QRS: narrow Electrophysiology A junctional pacemaker[teachingmedicine.com]

  • Atrial Fibrillation

  • Cor Pulmonale

    Virtually absent R waves in the right precordial leads (SV1-SV2-SV3 pattern).[lifeinthefastlane.com] Peaked P waves. Low QRS voltages (most obvious in the limb leads). Clockwise rotation (transitional lead V6).[lifeinthefastlane.com] Peaked P waves in the inferior leads 2.5 mm (P pulmonale) with a rightward P-wave axis (inverted in aVL) Clockwise rotation of the heart with a delayed R/S transition point[lifeinthefastlane.com]
