12 Possible Causes for Impaired Exercise Tolerance, P Wave Absent

  • 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]

  • Atrial Flutter

  • Left Bundle Branch Block

    The presence of a mid-QRS notching in more than two consecutive leads was a good predictor for the presence of SF (P 0.01), and when combined with an absent R-wave in lead[ncbi.nlm.nih.gov] V1, the presence of SF is very likely (P 0.001).[ncbi.nlm.nih.gov] CONCLUSION: Our data show that SF is present in 45.2% of LBBB patients, whereas it was absent in patients with non-LBBB.[ncbi.nlm.nih.gov]

  • 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]

  • Familial Atrial Fibrillation

    tolerance, degraded quality of life, impaired cognition or dementia, and tachycardia-induced cardiomyopathy. [8] Generally, while there is conflicting evidence in younger[rarediseases.info.nih.gov] […] diabetes, hypertension, and prior stroke, can further increase the risk of stroke. [7] Other complications that may be associated with AF include adverse hemodynamics, reduced exercise[rarediseases.info.nih.gov]

  • 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]

  • Atrial Septal Defect

    Inverted P waves in the inferior leads suggest an absent or deficient sinus node, as may be seen in a sinus venosus defect. 16,17 Right atrial overload is often present.[circ.ahajournals.org] Individuals with a sinus venosus ASD exhibit a left axis deviation of the P wave (not the QRS complex).[en.wikipedia.org] A common finding in the ECG is the presence of incomplete right bundle branch block, which is so characteristic that if it is absent, the diagnosis of ASD should be reconsidered[en.wikipedia.org]

  • Sinus Tachycardia

    The tachycardia ECG may be unremarkable, with P waves absent (hidden in the QRS).[patient.info] Before the RFCA, the brain natriuretic peptide was elevated, New York Heart Association functional class was worse, and there was an impaired exercise tolerance observed with[ncbi.nlm.nih.gov] ECG: Narrow QRS tachycardia of about 180 bpm with P waves often absent: they are hidden in the QRS, as atrial and ventricular depolarisation occur at the same time.[patient.info]

  • Ventricular Bigeminy

    The P wave will be absent. Premature Ventricular Complex - Bigeminy Premature Ventricular Complex - Trigeminy Premature Vent.[ekg.academy] The routine investigations should include resting 12-lead ECG, echocardiography, ambulatory Holter recordings, and exercise tolerance test.[karnatakaanaesthj.org] P Waves may be present or absent. P Waves are usually not seen if the rate is increased. If present, the P Waves have no relation to the QRS complexes of the V. Tach.[nurseslearning.com]

  • Atrial Bigeminy

    Every other beat is a premature atrial contraction (PAC) Junctional Tachycardia Heart Rate: Greater then 100 beats per minute (BPM) P Wave: Inverted, absent or after QRS PR[heartrhythmguide.com] The routine investigations should include resting 12-lead ECG, echocardiography, ambulatory Holter recordings, and exercise tolerance test.[karnatakaanaesthj.org] The P wave may be before or after the QRS complex or sometimes absent. What is a premature ventricular contraction (PVC)? An impulse originating in the ventricles.[unm.edu]
