Hypothyroidism is the condition in which the thyroid gland is unable to secrete sufficient quantity of its hormone thyroxine (T4). This disease is due to various causes such as 1.thyroid inflammation or thyroid cell necrosis due to a disease called Hashimoto Autoimmunity Disease.
This is one of the very common and very important causes of thyroid dysfunction.
Our body is equipped by nature with self-protection forces against invading pathogenic cells such as bacteria. When an invading pathogen enters into our body, our immune apparatus immediately responds to it by sending fighting cells to the area of invasion to kill the pathogen.
But due to some unexplained situation the fighting cells confused with healthy cells such as cells of the thyroid gland and kill them. This is known as Autoimmune Disease, or Hashimoto's Disease.
2.Medications for Hyperthyroidism such as Propylthiouracil, and Methimazole(Tapazole), Potassium or Sodium Iodide, and Radio Iodine (I131) if overdosed may cause thyroid gland damage.
3.Insufficient secretion of TSH from the pituitary due to some unknown pituitary disease
4.Thyroidectomy-Removal of the gland
4.Insufficient iodine intake.

In the lead-II recording, one can observe the elongated R-R interval which represents the presence of bradycardia (slower heart rate)
The absence of P-wave and the elongated P-R segment indicates the dysfunction of the atria.
Depression of ST-segment and the deformation of T-wave indicates the dysfunctions of the ventricles and the presence of angina.
Conclusively untreated long term hypothyroidism can precipitate many serious cardiac issues.

Hypothyroidism in ECG
In the above figure the effects of Hypothyroidism are apparent in examining the ECG.In the lead-II recording, one can observe the elongated R-R interval which represents the presence of bradycardia (slower heart rate)
The absence of P-wave and the elongated P-R segment indicates the dysfunction of the atria.
Depression of ST-segment and the deformation of T-wave indicates the dysfunctions of the ventricles and the presence of angina.
Conclusively untreated long term hypothyroidism can precipitate many serious cardiac issues.
