18 Possible Causes for Dyspnea at Rest, P Wave Absent

  • Ventricular Fibrillation

    Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Description The morphologic[ekg.academy] Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine)[ekg.academy] No P wave and no QRS complexes. This rhythm presents with a chaotic waveform which reflects the electrical chaos occurring within the heart.[ekg.academy]

  • Atrial Fibrillation

    P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[web.archive.org] P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic. Figure 1 Electrocardiogram showing atrial fibrillation.[aafp.org] P waves if arrhythmia is not captured on ECG then Holter monitoring in the outpatient setting these patients are hemodynamically stable telemitry in the inpatient setting[medbullets.com]

  • Pulmonary Disorder

    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]

  • Dextrocardia

    A 21-year-old female who was referred to our department because of progressive dyspnea on effort and at rest and minimal cyanosis is presented in this case report.[ncbi.nlm.nih.gov] , 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[litfl.com] At the admission, the patient was symptomatic at rest, with increased dyspnea on mild exertion, systemic hypertension, chronic atrial fibrillation, peripheral vascular disease[rcvmonline.com]

  • Wolff-Parkinson-White Syndrome

    The patients were asked to report any palpitations, asthenia, dyspnea (at rest, during effort, or both), dizziness, chest pain, blurred vision, or syncope.[content.nejm.org] Sometimes, the QRS complex may be normal, delta waves may be absent and p waves may be typically inverted on lateral and inferior leads.[symptoma.com] . • Ventricular Premature Contractions can initiate orthodromic tachycardia • On ECG findings, • the delta wave is absent, • QRS complex is normal, • P waves are inverted[slideshare.net]

  • Acute Aortic Regurgitation

    Eventually, patients experience dyspnea at rest, reflecting severe decompensated heart failure.[clinicaladvisor.com] The mitral A wave was absent in five patients with acute regurgitation.[ncbi.nlm.nih.gov] Patients with severe symptoms such as dyspnea or angina at rest or mild exertion not treated with surgery carry an annual mortality of 25%.[clinicaladvisor.com]

  • Sinus Bradycardia

    Mild to moderate dyspnea may be present at rest or from even the slightest exertion.[symptoma.com] In third-degree, or complete, SA block, the surface ECG is identical to that of sinus arrest, with absent P waves.[emedicine.medscape.com] In 3rd-degree SA block, conduction is blocked; P waves are absent, giving the appearance of sinus arrest.[merckmanuals.com]

  • Conduction Disorder of the Heart

    This should be done on an emergent basis if the patient is significantly hypotensive, or if they are severely symptomatic at rest (e.g., pre-syncope, dyspnea, chest pain,[cdemcurriculum.com] […] absence of sinus node activity (absent P waves) 3 seconds Sinus arrhythmia Normal, minimal variations in the SA Node's pacing rate in association with the phases of respiration[smartypance.com] Look for a wide QRS complex, equal or greater than 0.12 sec The QRS complex shape can be bizarre The P wave will be absent Sick sinus syndrome Population: Elderly Collective[smartypance.com]

  • Sinus Tachycardia

    Associated symptoms included palpitation, chest tightness, dyspnea and presyncope, either during rest or with exercise.[ncbi.nlm.nih.gov] The tachycardia ECG may be unremarkable, with P waves absent (hidden in the QRS).[patient.info] […] that is associated with symptoms like palpitations, dyspnea or dizziness in the absence of primary causes of tachycardia.[ncbi.nlm.nih.gov]

  • Multifocal Atrial Tachycardia

    Palpitations were virtually eradicated in these patients and all enjoyed significant improvements in rest and effort dyspnea, exercise tolerance and asthenia.[ncbi.nlm.nih.gov] ECG shows regular, normal-appearing QRS complexes without identifiable P waves or with retrograde P waves (inverted in the inferior leads) that occur shortly before ( 0.1[msdmanuals.com] Heart rate is 60 to 120 beats/min; thus, symptoms are usually absent.[msdmanuals.com]
