Maximal Treadmill Stress Testing for Cardiovascular Evaluation

Abstract

SUMMARYExperience with a maximal treadmill stress testing procedure which is relatively safe, simple, and reproducible is reported. It Circulation, Volume XXXIX, April 1969 Peak predicted pulse rates were chosen for detailed analysis. Information as to their previous health was only known for 284 executives previously examined and thought to be normal by history and resting ECG. Many of the remainder were sent for evaluation of known or suspected angina, and many were sent for screening prior to embarking on a physical fitness program. Careful questioning as to symptoms, medication, and previous cardiac disease was done to rule out unstable coronary insufficiency and congestive failure. In the group were 205 females and 795 males with ages varying between 7 and 83 years.No special attempt was made to standardize the time of day or the relationship of the last meal.The patients are prepared by applying gel (Lectrocardiographic Gel) to the Telectrode electrode and affixing these self-adherent electrodes to the upper part of the manubrium sterni and the standard left chest V5 position (CM-5).5 The cable attachments are then snapped to the electrodes and the cable is connected to a directwriting Sanborn electrocardiograph. The electrocardiographic complexes are monitored continually with an oscilloscope. An aneroid sphygmomanometer is placed on the right arm for measurements of blood pressure. A cardiotachometer gives a constant read-out of the heart rate. Oxygen, emergency drugs, and a DC defibrillator are available in the room.Resting electrocardiograms are taken while the patient is sitting and also while standing, before and after hyperventilation, and are used

The changes in maximal oxygen uptake (V̊O2MAX) induced by physical exertion during an Antarctic expedition depend on the initial V̊O2MAX of the individuals: a case study of the Brazilian expedition

“…Incremental tests on the treadmill were performed according to the protocol proposed by Ellestad & Kemp [15]. The incline of the treadmill was set at 10% in the first four stages and then it was increased to 15%, an incline that was maintained until the end of the test.…”

“…During the tests, the volunteers wore top (only women), shorts, socks and their regular tennis shoes. V̊O 2MAX was estimated using appropriate equations for both the treadmill [15] and cycle ergometer tests [18]. These equations provided V̊O 2MAX estimations in mL.kg −1 .min −1 .…”

Interdisciplinary Therapy and Decrease of Cardiovascular Overload in Obese Patients

“…Stature was measured with a stadiometer fixed on the wall with a resolution of 0.1 cm from Standard ES 2030-Sanny®. The Body Mass Index (BMI) [15][16] was then calculated. In addition, waist circumference (WC) and hip circumference (HR) were evaluated by a single trained evaluator using a Sanny® inelastic tape according to the protocol described by the World Health Organization.…”

“…Protocol of the test: The Ellestad 15 protocol was used for the ergospirometry test up to stage 3 to represent the daily activities in obese individuals. 16 Being stage 1 with a speed of 2.7 km/h; Stage 2 with a speed of 4.8 km/h and Stage 3 with a speed of 6.4 km/h, each with a slope of 10º and respective time of 3, 2 and 2 minutes each stage.…”

“…Treadmil exercise stress test was done using Ellestad's protocol (Ellestad et al 1969). Blood pressure and heart rate were measured every min for 10 min during the exercise and for another 8 min during the recovery.…”
