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]

Consequently, we can rule out the influences of change in respiratory frequency on the change in the HC in the present study. [jn.nutrition.org]

  Severity of coronary atherosclerosis correlates with the respiratory component of heart rate variability. Am. Heart J. 121:1070–1079, 1991. 47. Hinkle, L. E., S. T. Carver, and A. Plaken. [ms-se.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]

• Excitement

  Both effects result from abnormal excitation of the vagus nerve, and hence, the term used to describe the loss of consciousness that may result is vasovagal syncope. [healthcentral.com]

  The first critical test of this exciting hypothesis was to cut the vagus nerve. When Tracey and his team did, injecting the anti-inflammatory drug into the brain no longer had an effect on the rest of the body. [blog.bulletproof.com]

  The muscle fibers of the heart are excitable cells like other muscle or nerve cells, but have a unique property. [afpafitness.com]

  In particular, during atrial fibrillation in patients with atrioventricular reentrant tachycardia due to conduction through the bypass tract (AVRT) the ventricles may become pre-excited, posing a risk of degeneration into ventricular fibrillation. [clinicaladvisor.com]

• Hyperactivity

  Significantly, it decreases activity or hyperactivity between some critical brain regions. In this way, although pain awareness is increased, the negative experience or feeling of pain is decreased. [jonlieffmd.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]

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