It will typically be very relevant clinically. 7 m sy ra Pa t pa 38 Chapter 4 embolism, hypoxia, hypoglycemia, anxiety, and drugs. All are major disorders. Commonly used drugs that cause increased sympathetic activity include bronchodilators, inotropic infusions, and pressors. From the EKG, diagnose sinus tachycardia, and then evaluate the patient to determine its cause. Decreased parasympathetic activity is a much less common cause of sinus tachycardia and is most commonly related to atropine administration or poison ingestion.
All measurements of other waves are made relative to the baseline. 4 21 Physiology Review of the Heart’s Conduction System How to Measure Waves on the EKG Each little box is 1 mm tall (vertically). A wave that goes upward from the baseline is said to be positive. A wave that goes downward from the baseline is said to be negative. Measuring the distance of a positive wave’s peak from the baseline gives the amplitude (height) of the wave in millimeters. Measuring the distance of a negative wave’s lowest point from the baseline gives the amplitude (depth) of the wave in millimeters.
A common cause of increased parasympathetic activity is the vagal response. The vagal response can occur secondary to gastrointestinal (GI) stimulation during nausea and vomiting, drug treatment, the carotid reﬂex, or with direct therapeutic vagal stimulation for seizures or depression. 10 41 Heart Rate The Heart Rate in Atrial Fibrillation When the RR intervals are irregular, the best way to estimate the heart rate is by counting the number of QRS complexes in a 6-second block of time and multiplying that number by 10.
