Atrial Bigeminy
P wave with a PRI 120ms.[app.figure1.com]
This is visible on the ECG as an inverted P wave (“ retrograde P wave “), usually occurring after the QRS complex.[lifeinthefastlane.com]
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[lifeinthefastlane.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]
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]
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]

Supraventricular Tachycardia
Inverted P waves are sometimes seen after the QRS complex. These are called retrograde p waves.[acls-algorithms.com]
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]
Retrograde (inverted) P waves may also be seen. 5.[clinicaladvisor.com]

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[fprmed.com]
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[lifeinthefastlane.com]
However, the P wave is different from the sinus P waves.[aibolita.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]

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]

[…] 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]

Atrial Arrhythmia
BACKGROUND: Limited data are available about direct current cardioversion (DCCV) in Fontan patients. METHODS: Retrospective review of adult Fontan patients that underwent DCCV for atrial arrhythmias at Mayo Clinic, 1994-2014. Study endpoints were to determine procedural success, safety, and the freedom from[…][ncbi.nlm.nih.gov]

Acute Atrial Infarction
Abstract A patient with acute right ventricular infarction who showed hyposecretion of atrial natriuretic peptide (ANP) in spite of abnormally high right atrial pressure and who died of a severe low cardiac output syndrome is reported. Right atrial infarction, which was proven at autopsy, may be responsible for[…][ncbi.nlm.nih.gov]
