The patient with acute cardiovascular problems
Published in Peate Ian, Dutton Helen, Acute Nursing Care, 2020
A 12 lead ECG may be taken by a number of different members of the health care team. As with any procedure, the patient needs to be kept at the centre of the process. Informed consent is required, and privacy and dignity must be maintained. Chest hair may need to be removed with a single use razor to ensure good electrode contact. A semi-recumbent position of about 45 degrees is recommended, and the patient should be fully relaxed before the recording is commenced (SCST 2017).
Cardiac tests and procedures

An exercise test or stress test is used to assess the blood supply to your heart muscle. It also tests your fitness and strength, the state of your heart muscle, and your blood pressure response to exercise. It is used to test a variety of different conditions and is very useful and safe – we exercise patients within a day or two of a heart attack. Wear a tracksuit or similar light, comfortable clothes and shoes. Men may need to have their chest hair shaved. Women should wear a comfortable bra and bring a loose-fitting shirt because electrode pads are stuck on the chest and connected to an ECG machine. You will be exercised on either a cycle or a treadmill. Some cardiologists suggest that you stop some of your tablets (e.g. β-blockers) before the test, but others don’t. Do your best and let the technician or doctor know whether you want to stop or if you get chest ache or tightness or breathlessness. During the test your ECG and blood pressure will be recorded. The cardiologist will see you in clinic or one of the team will see you after the test to explain the result and tell you whether any other tests are necessary.
Performing an ECG recording

To optimize electrode contact with the patient’s skin and reduce ‘noise’, consider the following tips: removal of chest hair It may be necessary to remove chest hair in the areas where the electrodes are to be applied. Ensure the patient consents to this before you start. Carry a supply of disposable razors on your ECG cart for this purpose.light abrasion Exfoliation of the skin using light abrasion can help improve electrode contact. This can be achieved using specially manufactured abrasive tape or by using a paper towel.skin cleansing An alcohol wipe helps to remove grease from the surface of the skin, although this may be better avoided if patients have fragile or broken skin.electrode placement Correct placement of ECG electrodes is essential to ensure that the 12-lead ECG can be interpreted correctly. Electrode misplacement is a common occurrence, reported in 0.4% of ECGs recorded in the cardiac outpatient clinic and 4.0% of ECGs recorded in the Intensive Care Unit.

Echocardiographic analysis was performed to evaluate cardiac function using a high-resolution ultrasound imaging system with MS-250 probe (Vevo 2100, Visualsonics Inc., Toronto, Canada). First, the mice were anaesthetized with 2.5% isoflurane in a gas mixture of 5% CO2 and 95% O2. Then, the chest hair was removed with a depilatory cream. All of these measurements were performed in a blinded manner, and the methods here reference our previous study (Zhao et al. 2019). The ejection fraction (EF), fractional shortening (FS), left ventricular end-systolic volume (LVESV) and left ventricular end-diastolic volume (LVEDV) were measured using M-mode recording of the short-axis view. The maximum velocity of the mitral valve (MV) in early diastole and systole was evaluated using four-chamber echocardiography. The ratio of MV E/A was applied to reflect the changes in cardiac function.

Attachment of the electrodes to the chest required extensive shaving of chest hair especially among men. Since data was to be collected for seven continuous days, we pretested methods to secure the Actiheart to the chest such that the wire connecting the leads would not be hooked thereby dislodging the apparatus. Once the device was charged, and after shaving and preparing the skin, we used 3M Red Dot electrodes to secure the leads and then two overlapping 20 cm strips of 2″ Kinesiology Tape (Theraband, Akron OH) layered over the entire device. Ten of 27 applications required complete reapplication due to unsatisfactory signal. The device was checked twice per day and four required reapplication 3–4 days into data collection because the tape detached. Failure of the tape occurred after bathing and dressing. Neither the participants nor the nursing staff expressed problems with the Actiheart. Actiheart units were cleaned by soaking overnight in Cidex OPA solution (Johnson&Johnson, Markham ON, Canada) followed by soak and rinse in tap water.
Long-term outcome of a patient with paradoxical hypertrichosis after laser epilation

This is the first reported case documenting the natural progression of a patient with paradoxical laser-induced hypertrichosis over a significant length of time. This patient had near complete body LHR and reported an 80% clearance of lower body hair, no change in chest hair reduction and paradoxical growth of hair involving the upper arms, shoulders, and neck. We found the areas where patient had vellus hairs, mainly the upper arms and neck, were most affected.
