The amplitude of the wave did not c

The amplitude of the wave did not change when the frequency of the stimulation was increased because cardiac muscle is incapable of wave summation due to its relatively long refactory period the result support my prediction

It is only possible to induce an extrasystole during relaxation because cardiac muscle is able to depolarize only after repolarization

Wave summation and tetanus are not possible in cardiac muscle tissue because of the absolute refactory period of cardiac muscle. Cardiac muscle cells have long action potentials and long twitches. Preventing wave summation and tetanus

Amplitudo gelombang tidak berubah ketika frekuensi stimulasi meningkat karena otot jantung tidak mampu gelombang penjumlahan karena periode relatif lama refactory hasilnya mendukung prediksi sayaMungkin untuk menginduksi extrasystole selama relaksasi karena otot jantung mampu depolarize hanya setelah repolarisasinyaGelombang penjumlahan dan tetanus yang tidak mungkin dalam jaringan otot jantung karena periode refactory mutlak otot jantung. Sel-sel otot jantung memiliki panjang potensi tindakan dan panjang berkedut. Mencegah gelombang penjumlahan dan tetanus
