62 Possible Causes for Hypotension, P Wave Absent

  • Hyperkalemia

    Role of inducing K loss via the GI tract in the management of hyperkalemia Setting Recommendations Hyperkalemia with severe ECG changes (e.g. absent P waves, wide QRS complex[doi.org] An 85 year-old woman on a drug regimen of sotalol, valsartan, spironolactone, and trimethoprim-sulfamethoxazole presented to the emergency department with hypotension and[ncbi.nlm.nih.gov] Neurological effects Paraesthesia Weakness and flaccid paralysis (diaphragm is usually spared) Loss of reflexes Normal cranial nerves Normal sensory function Cardiovascular effects Hypotension[derangedphysiology.com]

  • Atrial Flutter

    Immediately post-cardioversion, he suffered severe hypotension with a depressed LV systolic function. IV dobutamine stabilized his blood pressure.[ncbi.nlm.nih.gov] Six weeks after his second procedure, while performing intense sprint intervals on a treadmill, he developed an abrupt onset of chest pain, hypotension, and cardiac tamponade[ncbi.nlm.nih.gov] Loading dose of landiolol hydrochloride 7.5 mg followed by 1.5-3 μg/kg/min continuous administration was given, which had decreased the conduction ratio to 2:1 without causing hypotension[ncbi.nlm.nih.gov]

  • Sinus Arrest

    Occasionally and when the P waves are absent for a relatively long time, escape beats appear, as other groups of myocardial cells undertake the pacemaking process for a brief[symptoma.com] Profound hypotension and a variety of dysrhythmias, including sinus arrest, have been reported in association with viral hepatitis, but most of these cases were described[ncbi.nlm.nih.gov] waves: Sinus P waves with basic rhythm; absent during pause PR interval: Normal (0.12 to 0.20 second) with basic rhythm; absent during pause QRS complex: Normal (0.10 second[aibolita.com]

  • Atrial Fibrillation

    P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[web.archive.org] Signs of acute atrial fibrillation are: hypotension, myocardial ischemia, decreased perfusion of vital organs and acute congestive heart failure (CHF).[rnceus.com] 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]

  • Beta-Blocker Toxicity

    Here, P waves are absent, QRS complexes narrow and the heart rate is around 40 beats per minute.[medicnow.com] Glucagon administration is indicated for hypotension, bradycardia or conduction impairment.[ww2.mc.vanderbilt.edu] Sotalol overdoses, in addition to bradycardia and hypotension, can cause torsade de pointes.[ncbi.nlm.nih.gov]

  • Accidental Hypothermia

    Abstract His bundle electrocardiography was performed on a patient with accidental hypothermia on whom the standard electrocardiogram (ECG) showed absent P waves, prominent[ncbi.nlm.nih.gov] Abstract Accidental hypothermia has a mortality rate of 30-80% and should always be borne in mind with comatose, hypotensive patients.[ncbi.nlm.nih.gov] Rewarming using renal replacement therapy circuit was unsuccessful because of severe hypotension.[ncbi.nlm.nih.gov]

  • Ventricular Fibrillation

  • Tachyarrhythmia

    P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[web.archive.org] One patient in the landiolol group showed hypotension and bradycardia, without serious consequences.[ncbi.nlm.nih.gov] 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]
