Double peak on r wave
Frequency determines the scalar energy of electromagnetic wave, E= hf=hc/r.
There are many different waves depending on the characterization category being studied. If waves are being characterized by the matter that they travel these waves include electromagnetic, physical, and longitudinal waves.
Assuming you are talking about Electrocardiogram readings, the ventricular contraction is represented by the 'R' wave. The R wave is so much higher because the left and right ventricles are made up of the largest and strongest muscles of the heart and show the largest electrical energies on the ECG when they are contracted.
Real/scalar waves and vector waves, commonly called longitudinal and transverse waves. The two waves are the scalar wave and the vector wave of a Quaternion Wave. Consider Quaternion Energy W = -vh/r + cP = [-vh/r, cP] the wave equations is the Second Derivative or Curvature: X2W = [d/dr, Del]2 [-vh/r, cP] = [(d2/dr2 - Del2), 2d/dr Del ] [-vh/r, cP] X2W = [-(d2/dr2 - Del2)vh/r - 2cd/dr Del.P, (d2/dr2 - Del2)cP + 2d/dr( Del -vh/r + cDelxP) ] The Longitudinal wave is the Scalar Wave (Del.P) and the Transverse Wave (DelxP) is the vector Wave.
Anterior MI
Poor R wave progression is a vague term used to describe a variation in the pattern formed by the QRS complexes in the chest or precordisl leads. The QRS complex represents the upward and downward deflections denoting the electrical discharge with each heartbeat. Normally the R wave is taller than the S wave by the 4th lead (V4). If the transition does not occur until the 5th or 6th precordisl lead then this is commonly referred to as poor R wave progression. It is used as a distinction from clearly normal patterns and clearly abnormal patterns. It may be found in normal hearts and can frequently be caused by improper placement of the electrodes during the recording of the ECG tracing.
Poor R wave progression is a vague term used to describe the transition in voltage in the precordial leads of an electrocardiogram (ECG). It is not a diagnosis but simply describes a pattern frequently noted. In a "normal" individual there is a progressive increase in the magnitude of the voltage in the leads from V1 to V4. When the peak voltage occurs later than V4 it is considered diminished or delayed. The normal criteria are very old and were likely based upon pathologic data. Current ECG technology includes computer interpretation. This particular pattern is usually reported out as "cannot rule out anterior myocardial infarction." The placement of the precordial leads is paramount in obtaining a reliable ECG pattern. Frequently the precordial leads are placed in the wrong position in haste to obtain the electrocardiographic tracing. Women particulary large breasted are most likely to have the leads improperly placed as the left breast usually overlies the 4th and sometimes the 5th intercostal space (where the leads should be placed). In summary, the term poor R wave progression is a vague term and not a diagnosis. Verification of proper leads placement should be the first response followed by echocardiography if there remains concern that there has been prior myocardial injury.
For an Arithmetic Progression, Sum = 15[a + 7d].{a = first term and d = common difference} For a Geometric Progression, Sum = a[1-r^15]/(r-1).{r = common ratio }.
The R-T segment is the portion of the EKG tracing from the R wave to the T wave.

In an arithmetic progression the difference between each term (except the first) and the one before is a constant. In a geometric progression, their ratio is a constant. That is, Arithmetic progression U(n) - U(n-1) = d, where d, the common difference, is a constant and n = 2, 3, 4, ... Equivalently, U(n) = U(n-1) + d = U(1) + (n-1)*d Geometric progression U(n) / U(n-1) = r, where r, the common ratio is a non-zero constant and n = 2, 3, 4, ... Equivalently, U(n) = U(n-1)*r = U(1)*r^(n-1).

in paced hearts, the ecg shows a sharp spike just before the qRs or R wave and the R wave will usually be widened if the ventricle is being stimulated directly. Similar to the appearance of the R wave in patients with complete heart block.
