What is Pacemaker?

-
A pacemaker is a small device that's placed under the skin in your chest to help control your heartbeat. It's used to help your heart beat more regularly if you have an irregular heartbeat (arrhythmia), particularly a slow one. Implanting a pacemaker in your chest requires a surgical procedure.

Types of pacemakers-

Depending on your condition, you might have one of the following types of pacemakers.

Single chamber pacemaker.-

 This type usually carries electrical impulses to the right ventricle of your heart.

Dual chamber pacemaker- 

This type carries electrical impulses to the right ventricle and the right atrium of your heart to help control the timing of contractions between the two chambers.

Biventricular pacemaker- 

Biventricular pacing, also called cardiac resynchronization therapy, is for people with heart failure with abnormal electrical systems. This type of pacemaker stimulates the lower chambers of the heart (the right and left ventricles) to make the heart beat more efficiently.

Hemophilia

Hemophilia is an inherited bleeding disorder in which the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery. Blood contains many proteins called clotting factors that can help to stop bleeding. People with hemophilia have low levels of either factor VIII (8) or factor IX (9). The severity of hemophilia that a person has is determined by the amount of factor in the blood. The lower the amount of the factor, the more likely it is that bleeding will occur which can lead to serious health problems. Causes Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot. This change or mutation can prevent the clotting protein from working properly or to be missing altogether. These genes are located on the X chromosome . Males have one X and one Y chromosome ( XY ) and females have two X chromosomes ( XX ). Male...

Menace of Fulani herdsmen in Nsukka: Lawyers to the rescue

When a situation gets out of hand, different measures could be devised to bring such situation under control. And nothing could be spared and no one overlooked in ensuring that positive solutions are found. Such is the situation in Igbo-Etiti LGA of Enugu State, where Fulani herdsmen and their cattle have allegedly wreaked a lot of havoc in the area, with the herdsmen allegedly committing various crimes ranging from armed robbery, rape to kidnapping. Aku Diewa Lawyers’ Forum (ADLAWF) in Igbo-Etiti L.G.A., Enugu State, has therefore sought legal and peaceful means to bring these nefarious activities to an end.
