Implantable Cardioverter Defibrillator

Implantable Cardiac defibrillators are invasive cardiac surgery advance in cardiac care.

Health science have made amazing technological advances in cardiac surgery over the past several decades. Modern equipment, procedures, and knowledge about heart disease risk allows us to save more patient lives than ever and bring the risk of dying from a heart attack to a lower figure.

Implantable defibrillators are another innovative solution to a serious cardiac problem. These devices are implanted in the chest to control sudden problems in patients who suffer from tachycardia, or an abnormally fast heart rhythm. A fast, out-of-control heart rhythm can strike suddenly and interfere with the heart’s ability to pump blood to the entire body. 

In a normally functioning human heart, the heart’s lower and upper chambers pump in sync with each other – delivering even and consistent blood flow. With heart failure brought on by tachycardia, something interferes with the electrical signals to the heart that dominate this natural rhythm and the chambers pump out of alignment.

When the heart chambers pump out of alignment, the heart is not able to deliver a adequate amount of blood to the whole body. The patient may begin to experience symptoms like dry cough, swelling of the ankles or legs, fatigue, and rapid or irregular heartbeat. Having a defibrillator implanted can greatly reduce the risk of dying of heart failure due to tachycardia. 

The defibrillator consists of a tiny chip within a metal case and two “lead” wires implanted in the heart by a heart surgeon. The unit can be programmed by a doctor and is generally safe. Cell phones and MRI devices can, however, interfere with defibrillator function, so it is recommended that patients use their cell phones on the side of the head opposite that which has the defibrillator implanted. Patients with defibrillators should also not have MRI scans.

Doctors perform innovative cardiac surgeries like defibrillator implantation, minimally invasive cardiac surgery, and heart valve replacement surgery. Defibrillators represent a continuing trend of life-saving advances in cardiac care, improving quality of life for patients and their families.

Mitral stenosis heart disease

-
It’s a frightening truth that innumerable people across the globe are becoming victims of heart diseases, day by day. Mitral stenosis is a kind of heart disease, which affects plethora of people, belonging to different geographical area, ethnicities, races, and cultures, etc.  Mitral stenosis is the disease inflicting the mitral or bicuspid valve of the heart. Our heart is made up of 4 chambers, and again divided into right sided chambers, and left sided chambers. Mitral valve is present between the 2 left sided chambers of the heart. Narrowing of the Mitral valve is known as Mitral stenosis.  Mitral stenosis causes: There are myriad causes of Mitral stenosis, and let’s talk about a few of them:  One of the most common causes of Mitral stenosis is another heart disease called Rheumatic fever. This disease has serious implications on the heart, along with many other organs of the body.  It adversely affects the valves of the heart, mainly the Mitral v...

Foods That Prevent Hypertension

Hypertension (HTN) refers to the increase blood pressure (above 120/80 mmHg). According to the May 2012 statistical report from World Health Organization, there are approximately 290,000 cases of maternal deaths with relation to Heart Disease caused by hypertension. 1/3 of the figure comes from India with 20% prevalence rate and Nigeria with 14% incidence rate. Juvenile Hypertension is a condition that affects children. The data taken from the WHO records show that in 10-year study (2002-2012), there are 7.6 million deaths yearly occurring to children with heart disease caused by hypertension. This simply tells everyone that hypertension is one of the leading causes of mortality deaths in the world. Everybody is not exempted for this case especially if they are engaged with several unhealthy lifestyle practices. In line with this, we will provide you with information regarding the preventive care for hypertension. It provides strict emphasis on the foods that can help ...

Juvenile Hypertension Essential Facts

-
High blood pressure in children is described as higher BP readings for about 95% compare to normal BP. This condition may occur to both male and female child. It usually affects a certain age group (14-18 years old). The juvenile hypertension may strike any child with varying weight and height, as well. Any case of high blood pressure that may occur to children who are below 10 years old is caused by other underlying cardiac problems. However, the causes of this vascular problem are the same with the hypertension to adults. These include overweight, failure to exercise, and possesses poor eating habits.  Modification of lifestyle and eating pattern can help reduce the chance of getting juvenile hypertension. But for other cases, pharmaceutical drugs will be given to stabilize the blood pressure.  Causes of Juvenile Hypertension There are two major groups of causes for juvenile hypertension. These include the modifiable and non-modifiable factors. For modifiable fac...
