If atrial epicardial wires are present, pacing the atrium at a more rapid rate allows verification of AV conduction. [misc.medscape.com]

Rarely, some individuals without known cardiac disease (young adults, well conditioned athletes) may present with a PR >0.2s that is physiologic. In this clinical presentation, administration of atropine invariably shortens the PR interval. [clinicaladvisor.com]

Obviously, if a child or young adult presents with symptoms such as syncope, or has an abnormal ECG, the phenotype is present. [hawaii.edu]

Subjects were required to answer aloud within 5 s after the presentation of each problem. The order of presentation was two serial subtraction problems, six arithmetic problems, and three additional serial subtraction problems. [ms-se.com]

A 56 year old male presents to the emergency department with chest pains, nausea and vomiting. His temperature is 37.2, blood pressure 110/70, heart rate 50, respirations 20, and oxygen saturation normal on room air. [healio.com]

• Hypotension

  Hypotension, or low blood pressure, is associated with increased nervous system activation and increased heart rate, but one type, hypovolemic hypotension, occurring after hemorrhage or certain drugs, induces a decrease in heart rate. [healthcentral.com]

  The moment infero posterior MI occur it stimualtes the vagus and a prompt bradycardic response occur .Many times the classical hypotension /bradycardia reaction is simply a reflection of heightened vagal tone. [drsvenkatesan.com]

  While atropine can be used to temporarily relieve the vagal hypertonicity, our patient is doing fine with no symptoms of bradycardia (which would be related to hypotension such as dizziness or syncope). [healio.com]

Digoxin is indicated in the treatment of atrial fibrillation, atrial flutter and heart failure (currently it is not a first line treatment). [pharmacologycorner.com]

Treatment In most instances, hypotension and fainting are relatively benign. If you feel all right, you do not have to do anything. Treatment depends on the initiating mechanisms. [healthcentral.com]

Understanding the causes of interpersonal disturbance within the disorder is, thus, important for developing treatments that can help ameliorate the misery defined by BPD. [grantome.com]
