Other contributors have said "On a ekg which abnormality results in a broad and deep q waves?" is the same question as "Why are the waves in an EKG labeled P QRS and T?" If you believe that these are not asking the same thing and should be answered differently, click here
this occurs with a premature beat known as a PAC (premature atrial contraction) A t wave is ventricular repolarization (the ventricle getting ready to beat again. A premature atrial contraction may...
left atrial contraction... the right atrial contraction is hidden by the left cause the left atria is bigger.... if the P wave is negative or m shaped or biphasic it could indicate that the right...
p-wave is a wave of depolarization that spreads from the SA node throughout the atria, and is usually 0.08 to 0.2 seconds (80-200 ms) in duration. The brief isoelectric (zero voltage) period after...
The QRS complex and the P wave are features of the electrocardiogram, which graphically displays the electrical activity of the heart. The P wave is generated when the atria, or upper chambers of the...
