Pacemaker is indicated for patients with bradycardia

Pacemaker is indicated for patients with bradycardia

The heart pacemaker was created as a substitute for the electrical part of the heart that makes it beat. To understand better, the heart must hit a certain sequence. The atria function as an antechamber (hence the name) that receives the blood. When it is full the door of the antechamber opens (the mitral and tricuspid valves), letting the blood enter the ventricle, from where it will be pushed to the rest of the body. An electrical warning causes the ventricle to contract and immediately before that the port / valve closes behind the blood so it does not return to the atrium. To govern this orchestra there is an electric impulse. It runs all over the atrium warning that the muscle needs to contract and then the entire ventricle warning that it also has to contract.

People who have blockages in this warning make the "gatekeepers" be distracted, and only open the door when you remember. Thus, the heart only beats sometimes, has flaws and even does not hit anymore.

People with a heart rate of less than 40 bpm (beats per minute) during the day or with pauses (times without a heart beat) greater than 3 seconds during the day, heart blockers (partial fainting or totals independent of symptoms), people who have bradycardia or dizziness with medications that are essential to their life are candidates for definitive pacemaker implantation.

O pacemaker implant is done in a surgical or hemodynamic center, lasts about two hours, and the person is usually discharged the next day. It can be placed just below the skin, in the chest, under the chest muscle, in the abdomen or even in the armpit (the patient should always discuss with his physician options that will make him more comfortable for his activities, as well as aesthetics and preference). > The electrodes are placed in the heart and a "bag" (store) is made to store the pacemaker pulse generator. The battery of this generator lasts on average eight years. And every three to six months the carrier should come to your doctor to evaluate the life of the device and whether the cables / electrodes that go to the heart are working well. Thus, it is possible to predict the timing of the change safely.

In addition, during routine consultations adjustments can be made according to patient use and the capabilities of each pacemaker. Most pacemakers feature intelligent functions that can be triggered to provide greater comfort to the wearer. This can be programmed and adjusted according to the daily requirement.

It is therefore important to monitor the cardiac arrhythmias when present and, if you are indicated for a pacemaker, be sure to perform the proper maintenance by visiting your doctor or at regular intervals. Remember to also talk about the activities that can be performed with the pacemaker, such as physical exercise, and what should be avoided in each case.

Developed in the 60s under the name of ANAVAR, oxandrolone was used as a medicine for male infertility. It was later used for the treatment of hepatitis, for growth stimulus, for the treatment of osteoporosis, for the recovery of tissue with burns and, currently, it is very much sought for the increase of muscle mass.

Chemotherapy: Measures Reduce Patient Exposure to Infections

Chemotherapy: Measures Reduce Patient Exposure to Infections

People who undergo chemotherapy are at increased risk for infections. This is because drugs used to kill cancer cells (called chemotherapy) may also impair the body's ability to produce all blood cells, including defense cells called leukocytes. The risk increases as more treatment sessions the person does, however, in some cases, doctors prescribe antibiotics preventively to people who are at high risk of infection.
