Hello Doctor. I am a 15 year old boy. I face pain in the back right side of my chest. It feels like something is poking me and like a burning sensation only at the back side of right chest. It actually pains when I hold my urine for a long time, it feels like that but I am not sure. It has started since I accidentally got the rice gone inside my wind pipe. I was eating and suddenly a grain of rice got inside my wind pipe and I felt difficulty breathing properly for at least 1 minute. I don't know if it came out or not. The grain of rice made me to suffer a lot. I had so difficulty breathing but I got fine after sometime. As soon as that incident took place there started a pain only at the back right side. I also get stomach pain near to the kidneys when I get up almost everyday. I feel that it pain because I hold urine for long an don't go out to pass the urine during mid night time as I sleep very nicely. I thought these pains are due to infection and started taking amoxicillin without doctor's prescription. S o Doctor can you tell me what my problem really is.

The heart's electrical conduction system plays a very important role in cardiovascular functioning. Also known as the atrioventricular (AV) conduction system, it regulates and controls the timing of the heartbeat.
How does the heart's electrical conduction system work?
There is a collection of electrical cells in the upper right atrium of the heart known as the sinoatrial (SA) node which acts as a natural pacemaker and generates electrical signals. These signals travel through specialized electrical pathways and stimulate the muscular walls of the heart to contract in a rhythmic manner. This gives rise to the heartbeat that pulses at a specific frequency every minute.
What is the effect of fluctuations in electrical activity on the heart?
The standard heart rate in human being ranges from 60 to 100 beats per minute. It slows down when a person sleeps and speeds up when one experiences physical or emotional heightening. These fluctuations are triggered by the brain or other systems of the body and signal the SA node to generate charges more rapidly or slowly. This leads to spikes and drops in the heart rate, depending on the nature of the situation.
What happens when there is dysfunction in the heart's electrical activity?
When the heart's electrical conduction system does not function properly, it leads to the occurrence of a condition known as arrhythmia or abnormal heart rhythm. This happens when electrical impulses are generated in an irregular manner and causes tachycardia (rapid heartbeats) or bradycardia (slow heartbeats) which takes place in jarring infrequent tempos.
What causes fluctuations in the heart's electrical activity?
There are various kinds of triggers that cause the heart rate to fluctuate. The exact nature of fluctuation also depends on the type of trigger. A few everyday examples of these causes are as follows:
- Exercise and strenuous physical activity increases electrical activity as the heart is required to beat faster so as to increase the supply of blood and oxygen to the muscles.
- Sleep and rest reduce heart rate as the body is not needed to exert itself.
- Release of adrenaline into the bloodstream causes the heart rate to spike up. If you wish to discuss about any specific problem, you can consult a Cardiologist.
I monitor my blood pressure three times today in same time after a gap of one. Minute, the first reading said is 103/ 94, then second 107/79, and last time it says 123/90, I dint not understand as it quickly gave different results, what does it mean.

Over the last few decades, the word cholesterol has assumed a different connotation. It has come to be known as a silent killer that spells doom for health. However, what we need to realize is that a certain amount of cholesterol is essential for the proper functioning of the body. The liver produces about 85% of the cholesterol that is required by the body normally. The ever changing food habits have introduced a lot of processed foods that are loaded with saturated fats. Along with this, reduced physical activity has led to accumulation of cholesterol in the blood.
The types of cholesterol are based on the density and we have 2 types of density that is Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL). LDL is more dangerous than HDL, called as bad and good cholesterol respectively. In addition, the triglycerides and lipoprotein are also critical indicators of overall cholesterol levels. Depending on a person's age, height and weight, normal levels are derived for each of these four.
Because of their density of the cholesterol molecules, as they are circulating in the blood stream, they tend to get sluggish and settle down along the walls of the blood vessels, referred to as plaque. This plaque attracts more and more cholesterol from the blood and the layer gets gradually thicker. This reduces the thickness of the blood vessels and in severe cases even completely blocks blood flow to important organs like the brain and heart, leading to severe conditions like stroke and heart attack respectively.
However, it is not always that all cholesterol is bad. It is one of the essential things for the proper body functions with the main functions listed below:
- Each cell in the body requires it to form the cell membrane, the protective layer around the cells
- Synthesis of vitamin D is done with the help of cholesterol, which is very essential for skin health
- It also helps in hormone formation. In addition to steroids, other hormones like testosterone, estrogen, cortisol require cholesterol as a main ingredient
- Formation of neurotransmitters and overall nerve function requires cholesterol. This ensures optimal neurological functioning.
So, as noted above, there are, both good and bad aspects to cholesterol. It is not all that dangerous a thing that it is made out to be. The trick is to maintain a good level of cholesterol so that the body's requirements are met, and at the same time, the harmful effects are kept at bay. Some important parameters to manage, include the percentage of bad cholesterol in the blood and the ratio of triglycerides to HDL in the blood. These are considered fair indicators of heart health and if need be, lifestyle changes and/or medications can be undertaken to manage overall health and reduce risk of heart disease and stroke.
