What is indicated when a very deep Q wave is observed in an ECG recording?
The usual cause of Q wave irregularities is a previous heart attack resulting in dead heart muscle tissue or thickening of the heart muscle possibly from insufficient blood flow to the heart. Consult a doctor if you havent already
What are some non living things that begin with the letter Q?
Quilt Quill
Why does the resting heart rate become smaller by exercising?
Because the stroke volume (amount of blood pumped per contraction) increases in the trained individual. Therefore to deliver the quantity of blood needed to support metabolism in the resting state, you heart needs to beat less frequently.

Malakas Street, Diliman, Quezon CIty. It is At the back of Philippine Heart Center
Does CQ10 good for heart disease?
Without any doubt,but the drug companies are far from happy about it ! CoQ10 is short for Co enzyme Q 10. This molecule is made in every cell in our body and is required for the body to make energy. This energy is needed to do all the work the body needs to do, weather it is to run a marathon, read a book, digest a meal, grow, recover from a cold, or just to type an answer to your question. The heart, being a big muscle, uses a lot of energy (and thus CoQ10) to do its work. Our body makes Co Q 10. We also get Co Q 10 from our diet, from muscles (which use a lot of energy and thus have a lot of Co Q 10 in them), AKA meat, being a primary source of dietary Co Q 10. The question isn't if Co Q 10 is good for our heart or any other cell in the body. Without Co Q 10 we would be dead. So yes, not only is it good, it is required. The question should be why would we need to take supplemental Co Q 10 if our body makes Co Q 10 and and we get it from food we eat. The first part of this answer is because under certain circumstances we don't make enough Co Q 10. The second part of this answer is we likely don't get enough through our diet, especially if we don't get enough whole foods in our diet. The main reason we find people needing supplemental Co Q 10 is because of medications that deplete Co Q 10 in our body. Statin medications for example, which are medications use to lower cholesterol, block our body's production of Co Q 10 which causes a deficiency of Co Q 10 in our body. This is why a lot of people on statins, especially high doses of statins, complain of being tired. Many other common medications can lower Co Q 10 in our body, such as beta blockers or some diabetic medications.

What changes can occur on ECG due to coronary artery disease?
The ECG shows ST elevation or depression and pathological Q waves. The pathological Q wave is a sign of an old infarct (heart attack) as the muscle doesn't conduct an impulse at a certain point.
Why is the q wave negative?
The Q wave is often negative because it reflects the depolarization of the interventricular septum from left to right in the heart, resulting in an initial negative deflection on the electrocardiogram. This is a normal finding in most individuals and is considered a part of the normal electrical activity of the heart.
What are three different ways an EKG might warn of a heart problem?
ST elevation would indicate a heart attack (MI). A Q wave would indicate an old MI. A fast heart rate >120bpm may be significant if the patient is not already being treated for conditions such as SVT. Bradycardia <60bpm may require pacing.
What does a small p wave on a ecg mean?
nothing... a nonexistent Q wave represents a possible heart attack in the past in the location of whatever lead its in. However, patients that are barrel chested or just plain big can throw off an EKG.
What is occurring within the heart during each part of the EKG?
The P wave measures the atriums. The Q,R,S Complex measures ventricles. The T wave measures repolarization.
What does QR stand for?
QRS in the context of cardiovascular health has reference to the electrical pattern of the heart. This is readily seen on an ECG (electrocardiogram). The Q wave is the first downward deflection after a P wave, the R wave is the first upward deflection following a P wave, and the S wave is the downward deflection following the R wave. Taken together the QRS complex represents the electrical activity of the heart during systole: the phase of the heart during which ventricular emptying occurs.
What is the first wave of an ECG?
The first wave of an ECG is the P wave, which represents atrial depolarization as the electrical impulse spreads through the atria. It is the initial wave seen in a normal heart rhythm.
Which label on the model presents a wave length?
q
What is a set of rational numbers that begin at 0?
It could be the set denoted by Q- (the non-positive rationals) or Q+ (the non-negative rationals).
What happens when an infrared wave strikes an object?

How do you identity the opposite and the absolute value of a rational number?
The additive opposite of the rational number q is -q. One of q and -q must be non-negative and that is its absolute value.
