The NP placed the patient on 3 L of oxygen via nasal cannula with positive effect as the oxygen saturation rose to 96% and the respiratory rate decreased to 18 breaths/minute. Her normal caloric intake was about 1,750 calories. View all chapters in Cardiac Arrhythmias. In a normal ECG, the S wave transitions to the R wave looking prominent. Informed by the ECG, the NP expeditiously and appropriately managed the patient's care. Vital signs recorded throughout hospital stay. Even an axis within the range from +90 to +110 degrees may indicate an abnormality in older patients, particularly if other ECG abnormalities coexist. Patients with tachy-brady syndrome may also necessitate rate controlling drugs (e.g beta-blockers) and anticoagulation (if atrial fibrillation or flutter can be verified). A cardiology consult was necessary because the patient experienced a small pericardial effusion. Meanwhile, the term bradycardia is used to describe a heart rate thats slower than typical. You should start feeling better soon after you receive effective treatment for sinus bradycardia (either medications or temporary pacing). In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between 30 and 90.
