In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.
what causes abnormal t waves
it is not risky for life
The change from nonspecific T wave abnormalities to inverted T waves in the lateral leads of the ECG from September 26, 2017, suggests a possible progression in the underlying cardiac condition. Inverted T waves can indicate ischemia, strain, or other structural changes in the heart. This alteration may warrant further investigation to assess the patient's cardiac health and determine any necessary interventions. It’s essential to correlate these findings with clinical symptoms and other diagnostic results for accurate interpretation.
not inverted
Reflected waves can be inverted or not depending on the medium through which the wave is traveling. In a denser medium, like a solid, waves are typically inverted upon reflection. In a less dense medium, like air, waves may not be inverted upon reflection.
Reflected but not inverted
Handbags featuring an inverted "T" on the front are made by the luxury brand Tod's. The inverted "T" is part of the brand's logo, which is recognized for its high-quality leather goods and craftsmanship. Tod's is particularly known for its stylish handbags, shoes, and accessories.
If you mean who invented the telephone, not inverted, then it was Alexander Graham Bell.
The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.
