48 Possible Causes for Cyanosis, Inverted P Wave

  • 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] […] portion of the P wave in V1.[lifeinthefastlane.com] […] an interventricular conduction delay mimicking LBBB — however, this is not LBBB as the morphology is not typical and there are small Q waves in V5-6 ( the presence of Q waves[lifeinthefastlane.com]

  • Spontaneous Pneumothorax

    An ECG was administered; findings indicated reversal of the arm leads (right axis deviation and inverted P waves in lead I), but there was no actual limb lead reversal present[ncbi.nlm.nih.gov] CONCLUSIONS: The most severe forms of pulmonary alveolar proteinosis, in which hypoxemia and cyanosis occur, have a high mortality risk during anaesthesia and whole lung lavage[ncbi.nlm.nih.gov] […] pressure bleeding breath sounds Bronchoscopic examination bullae cent chemical pleuritis chest wall clavicles collapsed lung condition of lungs Constitutional symptoms coughing cyanosis[books.google.com]

  • Pulmonary Emphysema

    The most typical ECG findings in emphysema are: Rightward shift of the P wave axis with prominent P waves in the inferior leads and flattened or inverted P waves in leads[lifeinthefastlane.com] This compares with the hypercapnoea and cyanosis of chronic bronchitis with patients referred to as "blue bloaters".[radiopaedia.org] Other symptoms of emphysema include the following: Cyanosis (bluish tint to the lips, fingertips, and skin; caused by low levels of oxygen [O2] in the blood) Edema (swelling[healthcommunities.com]

  • Cor Pulmonale

  • Supraventricular Tachycardia

    Inverted P waves are sometimes seen after the QRS complex. These are called retrograde p waves.[acls-algorithms.com] Updated 21 Nov 2018 Apnoea is defined as no effective respiratory effort for 20 seconds or for 10 seconds if associated with bradycardia ( 100 bpm), oxygen desaturation, cyanosis[health.vic.gov.au] 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]

  • Patent Foramen Ovale

    In rare cases, a baby with a PFO will develop a bluish skin tone (cyanosis) when straining or crying.[childrenshospital.org] If babies with PFO have cyanosis, it is usually because they have other heart defects, as well. What are the risks?[texasheart.org] In some cases, babies with PFO may have a bluish tint to their skin (called cyanosis ) when they are crying or straining during a bowel movement, but this is a very rare sign[texasheart.org]

  • Atrial Arrhythmia

    Other symptoms experienced can be inadequate blood flow which can cause feelings of dizziness, chest pain, fainting, dyspnea, pallor, fatigue, nervousness, and cyanosis.[physio-pedia.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] Depending on the severity of the malformation and the arrhythmia, SVTs can produce cyanosis and severe symptoms or death.[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]

  • Pulmonary Disorder

    The most typical ECG findings in emphysema are: Rightward shift of the P wave axis with prominent P waves in the inferior leads and flattened or inverted P waves in leads[lifeinthefastlane.com] Inspection should focus on Signs of respiratory difficulty and hypoxemia (eg, restlessness, tachypnea, cyanosis, accessory muscle use) Signs of possible chronic pulmonary[msdmanuals.com] Less oxygen in the blood can cause a bluish tint (cyanosis) to the lips and fingernails, while a buildup of carbon dioxide, due to the inability to exhale properly, can cause[sharecare.com]

  • Transposition of the Great Vessels

    P waves in lead 2, widened QRS complexes, and upright T waves in the precordial leads, beginning either in RV4 or V1.[pediatrics.aappublications.org] This mechanism leads to profound and life-threatening cyanosis.[symptoma.com] The number of clinical signs (poor general status, cyanosis, respiratory distress, S2 increased and single, murmur, classical chest roentgenogram, abnormal ECG) present in[ncbi.nlm.nih.gov]
