“…Also, increased precordial voltages may be present in thin adult males who are not athletes and also in Blacks, where the increased voltages appear to be a racial variation in the ECG. 28 Nevertheless, autopsy studies of athletes who died accidently 29 or of noncardiac disease have shown heart weights to be consistently greater than normal and, therefore, support the contention that hearts of athletes actually undergo an increase in mass due to physical training. Reindell et aL2@ found heart weights to be 350-540 grams (normal <350 g) in the 34 athletic subjects that he studied.…”

Although earlier electrocardiographic and roentgenographic studies suggested that the heart of trained athletes differed from that of nonathletes, little was known of the cardiac dimensions of the athlete's heart until the advent of echocardiography. Echocardiographic studies have demonstrated that trained athletes may have increased left ventricular mass and that the structural change accounting for this increase is related to the type of physical conditioning. Athletes participating primarily in isotonic exercise have an increase in left ventricular end-diastolic volume with little or no increase in left ventricular wall thickness whereas those athletes participating primarily in isometric exercise have an increase in left ventricular wall thickness associated with normal left ventricular end-diastolic volume. Comparisons between echocardiographically determined cardiac changes in college and world class athletes were made, and the electrocardiographic and chest roentgenographic changes present in the athlete's heart syndrome were reviewed.

The electrocardiogram is an inexpensive adjunct for assessing target organ damage in hypertensive patients. The gender-specific Cornell voltage criteria (men: R(aVL) + S(V3) >35 mm; women: R(aVL) + S(V3) >25 mm) have better overall accuracy than the often-used Sokolow-Lyon or Romhilt-Estes criteria. One of the earliest electrocardiographic findings of hypertensive heart disease is a duration of the negative phase of the P wave in chest lead V1 of >0.04 seconds, a manifestation of left atrial enlargement or abnormality. There is no other cardiovascular risk factor more potent than left ventricular hypertrophy with a "strain pattern." Despite limitations in determining hypertensive heart disease, the electrocardiogram provides other information that is useful in the management of patients with hypertension.

“…It means that the ECGs are different between individuals. Studies conducted in [9] prove that the distinctiveness of ECG are influenced by factors such as gender [10], age, blood mass-torso, torso-air conductivity [11], body shape, geometric shape of the heart and race [12].…”

New Heart Features for More Effective Human Identification

Biometric verification is a process to authenticate whether the subject is what it claims to be, based on the characteristics of the human body. These characteristics must meet seven (7) conditions to enable them to be used in a practical biometric system. These conditions are namely distinctiveness, performance, collectability, acceptability, universality, circumvention, and permanence. Electrocardiogram (ECG) is a human body characteristic measured from the heart that meets these seven conditions. Choosing the correct features from the ECG is important to get a high authentication rate. This paper proposed a new algorithm known as Bipolar Slope Feature (BSF) for ECG features selection. It is developed based on the relationship of slopes between several locations in a complete ECG cycle. The Receiver Operating Characteristic (ROC) curve is used to measure the effectiveness of this technique for the application of biometric verification.
