36 Possible Causes for Fainting Spells, Inverted P Wave

  • Supraventricular Tachycardia

    Inverted P waves are sometimes seen after the QRS complex. These are called retrograde p waves.[acls-algorithms.com] spells Sometimes, there are no symptoms.[ucsfhealth.org] A distinguishing characteristic of orthodromic AVRT can therefore be an inverted P-wave (relative to a sinus P wave) that follows each of its regular, narrow QRS complexes[en.wikipedia.org]

  • Atrial Arrhythmia

    spells.[betterhealth.vic.gov.au] You may not be getting enough blood to your brain and other organs which may cause weakness, fatigue, dizziness, fainting spells, swelling of the legs, and shortness of breath[a-fib.com] Symptoms are not always obvious but may include palpitations or a fluttering heartbeat, irregular heartbeat, chest pains, dizziness and fainting spells.[betterhealth.vic.gov.au]

  • 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] 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]

  • Cor Pulmonale

    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] Symptoms you may have are: Fainting spells during activity Chest discomfort, usually in the front of the chest Chest pain Swelling of the feet or ankles Symptoms of lung disorders[nlm.nih.gov] As the disease worsens, the following symptoms may occur with lighter activity, or even while you’re resting: 4 Fainting spells with activity Chest discomfort and/or chest[inogen.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] […] or light-headed spells Palpitations Leg swelling Call your doctor immediately if you have chest pain.[drugs.com] […] portion of the P wave in V1.[lifeinthefastlane.com]

  • Hypertrophic Cardiomyopathy

    New subtype of apical hypertrophic cardiomyopathy identified with nuclear magnetic resonance imaging as an underlying cause of markedly inverted T-waves.[doi.org] Patients who have family history of sudden cardiac death ; unexplained fainting spell; severe thickening of heart muscle or dangerous heart rhythm, are considered to be at[nhcs.com.sg] A "near-miss" sudden cardiac death (a life-threatening abnormal rhythm that self-converts) may appear to be a "fainting spell."[mottchildren.org]

  • Bradycardia

    This usually appears on an EKG with a normal QRS complex accompanied with an inverted P wave either before, during, or after the QRS complex. [3] An AV junctional escape is[en.wikipedia.org] Or you may also have fainting spells, dizziness, weakness, or an unusual lack of energy. How is it diagnosed?[cardiacsolutions.net] This test helps your doctor better understand how your bradycardia contributes to fainting spells.[mayoclinic.org]

  • Wolff-Parkinson-White Syndrome

    Therefore, a circuit is established, being seen as a tachycardia, with normal QRS but with inverted P waves (because of retrograde atrial activation).[web.archive.org] spells.[houstoncardiovascular.com] If the disorder is untreated, and particularly if you have other heart conditions, you may experience: Fainting spells Fast heartbeats Rarely, sudden death[mayoclinic.org]

  • Atrial Flutter

    All patients had documented type I AFL, defined electrocardiographically as inverted P waves inscribing saw-tooth pattern in inferior leads (lead II, III, aVF), and upright[kjim.org] spells[saintlukeshealthsystem.org] Retrograde atrial conduction produces: Inverted flutter waves in leads II,III, aVF Positive flutter waves in V1 – may resemble upright P waves Clockwise Reentry.[litfl.com]

  • Heart Block

    The initial electrocardiogram shows bradycardia with inverted T waves from V 2 -V 5. Figure 2 Progressive changes.[bmcresnotes.biomedcentral.com] But when a block causes the heart to beat too slowly, it can cause symptoms such as tiredness and fainting spells.[uofmhealth.org] As a result some patients with a second degree heart block will be symptomatic and present with fainting spells, lightheadedness and dizziness.[symptoma.com]
