92 Possible Causes for Inverted P Wave, Palpitations

  • Supraventricular Tachycardia

    Inverted P waves are sometimes seen after the QRS complex. These are called retrograde p waves.[] […] of SVT can be nonspecific and varies based upon age with infants demonstrating fussiness or irritability and older children reporting vague perceptions of tachycardia or palpitations[] 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[]

  • 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[] Symptoms include palpitations and fainting after physical activity.[] At a clinic visit 5 months later, she had received no ICD shocks and reported no symptoms of severe palpitations.[]

  • 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[] A 64-year-old man was incapacitated by frequent attacks of palpitation following swallowing.[] 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[]

  • Atrial Arrhythmia

    After 3 minutes, the palpitations stopped, the heart rate changed to a sinus rhythm, and the ventricular rate was 100 beats/min.[] Symptoms during arrhythmia were palpitations while exerting (88%), reduced physical ability (87%), palpitations at rest (86%), shortage of breath during exertion (70%) and[] Symptoms of Atrial Fibrillation Palpitations Chest Pain Decreased blood pressure Weakness Lightheadedness Shortness of breath Only a few years ago, people suffering from this[]

  • Premature Atrial Contractions

    wave is abnormal Premature (earlier than expected) Morphology different than normal P wave Inverted P wave suggests atrial source near AV junction Nearly normal P waves suggest[] , can cause palpitations.[] PACS arising close to the AV node (“low atrial” ectopics) activate the atria retrogradely, producing an inverted P wave with a relatively short PR interval 120 ms (PR interval[]

  • Atrial Tachyarrhythmia with Short PR Interval

    Diagnostic criteria include PR interval of no more than 120 ms, normal QRS complex duration, a normal or inverted P wave, and paroxysmal supraventricular tachycardia (PSVT[] Less commonly perceived as palpitations).[] She was euthyroid; ECG revealed regular rhythm with inverted P waves, short PR interval, absent delta waves with normal QRS morphology ( Figure 1 ).[]

  • Atrial Bigeminy

    P wave with a PRI 120ms.[] We call these episodes " palpitations ".[] .  58 year old male Mr.Kannan, who came to hypertension OP for routine checkup No H/o chest pain, palpitation or syncope Known smoker for past 20 years – 10 cigarettes[]

  • Atrioventricular Junctional Rhythm

    Retrograde inverted P waves with short PR intervals and a heart rate of 94/minute denotes to accelerated junctional rhythm. Click here for a more detailed ECG ECG 3.[] The indications of electrophysiology study were nonspecific palpitation (n 5), unexplained syncope (n 6), postablation of accessory pathways (n 4), and postmodification of[] Note the inverted P waves that precede each QRS complex, with a rate of 115 bpm.[]

  • 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[] A 46-year-old man was admitted to our hospital for near syncope and palpitations.[] Retrograde atrial conduction produces: Inverted flutter waves in leads II,III, aVF Positive flutter waves in V1 – may resemble upright P waves Clockwise Reentry.[]

  • 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).[] She reported a 90-pound unintentional weight loss, increased appetite, irritability, night sweats and palpitations for 2 months.[] He had not experienced palpitations, but a normal electrocardiogram was a prerequisite for enrollment in a professional soccer school.[]
