Premature atrial complexes (PAC) dysrhythmia has a cardiac complex that occurs too soon and may have abnormal p waves, but other than being ''early,'' has no other abnormal features.
<h3>What is Cardiology?</h3>
- Cardiology is a field of medicine that deals with problems with the heart and cardiovascular system.
- The term "cardiology" comes from the Ancient Greek words "kardi" (heart) and "-logia" (study).
- Heart failure, valvular heart disease, congenital heart defects, coronary artery disease, and electrophysiology are all covered in the field's spectrum of medical diagnosis and treatment.
- Cardiologists are among the professionals in internal medicine who work in this area.
- Pediatricians that specialize in cardiology are known as pediatric cardiologists.
<h3>Why does cardiac happen?</h3>
- Nearly all heart conditions that are known to exist can result in cardiac arrest.
- The electrical system of a damaged heart malfunctions most frequently during cardiac arrests.
- An aberrant heart rhythm like ventricular tachycardia or ventricular fibrillation is brought on by this defect.

Reproductive Method </h2>
Explanation:
<em>The rank in order from the most specific which is following .</em>
<em>(1) Reproductive isolating mechanism</em>
<em>(2) Sperm-egg incompatibility in sea urchins</em>
<em>(3) Gametic isolation </em>
<em>(4)Prezygotic isolating mechanism</em>
<em>(1) Reproductive isolating mechanism-</em> The components of regenerative confinement are an assortment of transformative instruments, practices and <em>physiological procedures basic for speciation.</em> They keep individuals from various species from delivering posterity, or guarantee that any posterity are sterile.
(<em>2) Sperm-egg contradiction in ocean urchins-</em> Bindin is a gamete acknowledgment protein known to control species-explicit <em>sperm-egg grip</em> and layer combination in ocean urchins.
<em>
(3)Gametic isolation - Prezygotic hindrances </em>keep preparation from occurring. Gametic disengagement is a sort of prezygotic hindrance where the<em> gametes (egg and sperm) </em>come into contact, yet no preparation happens. Gametes might be not able to remember each other in various species
<em>
(4) Prezygotic isolating mechanism- </em>while postzygotic segregation forestalls the arrangement of rich posterity. Prezygotic systems incorporate environment segregation, mating seasons, "mechanical" disconnection, gamete detachment and conduct seclusion.

Further Explanation:
Scientific investigations usually begin with observations. These are typically something that would catch the researcher’s attention. Then, the scientist comes up with a hypothesis which is a testable explanation for the phenomenon or what’s occurring a prediction is usually made based on the hypothesis.
A prediction of the outcome is usually made based on the hypothesis, after which it is tested via an experiment. The scientist then use the results to make new hypotheses or predict certain outcomes.
