What else can I help you with?
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 is the first negative after a p wave in a normal cardiac cycle?
The first negative deflection after a P wave in a normal cardiac cycle is the Q wave, which is part of the QRS complex. The Q wave represents the initial depolarization of the interventricular septum and is typically a small downward deflection. It is followed by the R wave (upward deflection) and then the S wave (downward deflection), completing the QRS complex that corresponds to ventricular depolarization.

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.

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 Q R and S wave?
Q, R, and S waves are components of the QRS complex in an electrocardiogram (ECG), which represents the electrical activity of the heart during ventricular depolarization. The Q wave is a small negative deflection, the R wave is a large positive deflection, and the S wave is a negative deflection that follows the R wave. Together, these waves indicate the heart's response to electrical signals and are crucial for diagnosing various cardiac conditions. The QRS complex typically lasts between 0.06 to 0.10 seconds in a healthy individual.
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?
I believe it is the P Wave. A good way to remember is all of the Waves are in alphabetical order. P Wave, Q-R-S Waves and the T Wave
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 does acute mean in ecg?
In the context of an ECG (electrocardiogram), "acute" typically refers to a sudden onset of changes in the heart's electrical activity that may indicate a new or recent cardiac event, such as a myocardial infarction (heart attack). Acute changes can include the presence of ST-segment elevation or depression, T-wave inversions, or the development of new Q waves. These findings often require immediate medical attention to assess and manage the underlying condition effectively.
